Discover the Importance of Surface Tension

Discover the Importance of Surface TensionSurface tension is a key term to understand when it comes to organic chemistry. It simply states that water is a liquid and is held in the center of the glass as it tends to fall to the bottom of the container. Due to the liquid's solid nature, it tends to bead up at the surface of the liquid in the container when the surface tension of the liquid is reduced.Another thing to understand is that water can be described as being on the dry or wet side of the environment's surface tension. When water evaporates, it leaves a film of vapor that remains on the surface. This allows water molecules to evaporate from the water by spreading out and forming larger droplets. This all-important substance actually does this even with the solids present.This phenomenon is known as the hydrophobic properties of water. Water also has hydrogen bonds, which means that it has two hydrogen atoms surrounding the one oxygen atom. That means that each molecule of wate r has the potential to hold more than one atom of water molecules.This means that there are more bonds between the molecules and less in between them. With this property, the hydrophobic property, there is less interaction between water molecules and they tend to stick together more easily when they are in a liquid state. This interaction between molecules can be thought of as a weaker form of water's surface tension.As hydrophobic properties get weaker with time, they can become less effective in repulsing water molecules that are too close to each other. This is due to other changes taking place in the nature of the molecule. Changes such as breaking up and forming into molecules that include hydrophobic properties.Water molecules can actually develop smaller ones when there is too much force being applied to them. These are known as small water molecules, because they tend to have a smaller size than the larger molecules that have already been formed. When the larger molecules co me together, they tend to get stuck together, and then there is a decrease in the overall water molecules' surface tension.Thus, the term surface tension is used for a solid substance that is held in contact with the surface of a liquid by the molecules of water. This property is generally described as being close to the liquid's surface when there is too much force being applied to it. Therefore, surface tension is the reason that water molecules tend to stick together when they are at a liquid's surface, and it is also the reason that the mass of the water is typically less than the mass of the molecules.

Critical Reasoning Question 5-MURDER - Private Tutoring

Critical Reasoning Question 5-MURDER BobbiM Feb 2, 2014 Statistics show that more than half of the nations murder victims knew their assailants; in fact, 24% last year were killed by relatives.  Nor was death always completely unexpected.  In one study, about half the murder victims in a particular city had called for police protection at least 5 times during the 24 months before they were murdered.  Nonetheless, most people are more likely to fear being killed by a stranger in an unfamiliar situation than by a friend or relative at home. Which of the following, if true, best explains the reaction of most people to the likelihood of being murdered? A.  Statistics are likely to be discounted no matter what the source, if their implication seems to run counter to common sense. B.  In the face of such upsetting problems as murder and assault, most people are more likely to react emotionally than rationally. C.  A study taken in only one city is not likely to have an effect on attitudes until similar studies have been undertaken at the national level and have yielded similar results. D.  Most people do not consider themselves to be in the high-risk groups in which murder occurs frequently between relations, but do see themselves as at least minimally susceptible to random violence. E.  People who seek police protection from relatives and friends are often unwilling to press charges when the emotions of the moment have cooled. The correct answer is: D Most murder victims were killed by people they knew, yet most people are more likely to fear being killed by a stranger.  The best way to explain this apparent contradiction is (D):  Most people dont believe they fall into the high-risk groups containing murderous friends and relations, but they do think they could be victims of random violence. As for (A), did these people find it counter intuitive that most murder victims knew their killers?  We dont know, so we cant assume they dismissed the statistics.  (B)s too vague to explain the discrepancy.  In light of the statistics, peoples fear of strangers seems irrational, but is it emotional?  A more emotional response might be to become terrified of being killed by ones spouse or best friend.  (C) fails because national statistics already exist, as the firs sentence makes clear.  Finally, (E) might explain why people who knew they might be killed ended up dead, but it doesnt resolve the discrepancy at hand.

Good Books II More Reading Recommendations for High School Students

Good Books II More Reading Recommendations for High School Students With the success of our last list, we’ve added some more recommendations from AJ leaders. As a reminder, here are the ground rules: the only requirements were that the books be appropriate for high-school-aged readers, and that they not be books that regularly show up on high school reading lists. Fiction and nonfiction, memoir and sci-fiâ€"it’s all here.Happy reading!Marina by Carlos Ruiz ZafónRecommended by Tala el-FahmawiWe are doomed to remember what never really happened. Marina is a beautiful Gothic tale that perfectly combines horror, mystery and romance. It is a heart wrenching tale that will keep you turning its pages searching for answers. While reading this novel, I found my eyes watering, my heart racing and my mind refusing to sleep. It is a book you will think about long after you finish the last page. A true masterpiece.The Book Thief by Markus ZusakRecommended by Kristin JusiAs a lover of books, this novel made me appreciate, well, books! A fantastic piece of his torical fiction, The Book Thief is a pretty easy read about a young girls experience in Nazi Germany, and in my opinion, beautifully written.Hans Christian Andersen: The Complete Fairy TalesRecommended by Nieka BrightDont let the name deceive you; these tales are brimming with real life lessons. To quote someone wise, If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.”Flight Behavior by Barbara KingsolverRecommended by Stephanie SimonIf you liked The Bean Trees and Animal Kingdom, you should check out this tale from Barbara Kingsolver about our changing world. Not only does it dazzle you with forest ecosystems and the migration patterns of monarch butterflies, it also deftly explores how culture shapes our views about science and the world around us. Through engaging characters and accessible prose, Kingsolver draws us in to explore the tension between scientific and cultural views, challenging u s to think about how we acquire our own deeply-held beliefs.Foundation by Isaac AsimovRecommended by David MasseyScience fiction with great twists!Rosencrantz and Guildenstern Are Dead by Tom StoppardRecommended by Sebastian von ZerneckHave you ever felt like you were just a minor character in someone elses story? This is the book for you. A re-telling of Shakespeares Hamlet from the perspective of two secondary characters, Rosencrantz and Guildenstern Are Dead is a quintessential postmodern play: innovative, mind-bending and absolutely hilarious.My Ántonia by  Willa CatherRecommended by Carmel RichardIm currently re-reading this book and falling in love again! What sets Willa Cather apart as an author is her ability to paint a picture almost impressionistically with a few brushstrokes of her pen, as well as her power to transform a web of vignettes into a full-fledged novel through her effortless encapsulation of universal themes within the eccentricities of unadorned characters. In this story, she does more. She binds all the characters together through the magnetism of a single central figure. This the story of Ántonia Shimerda, an immigrant girl blossoming into a woman against the sparse landscape of 19th century Nebraska. This is the story of life and death, joy and grief, self-discovery, but most of all undying memory. Its Cathers masterpiece, in my opinion. Highly recommend!

Tutor Nerds

Tutor Nerds eNotes: A Literary Companion Many high school students find it difficult to get through the books on their reading list, whether it’s for a standard 9th grade English class or for an AP English class (READ: Ask a Nerd! Taking the AP Exam). There are many options available and some of them are better than others. One option to consider is eNotes. The Great Books List eNotes offers over 40,000 study guides for books on the Great Books list. Although these can be useful for anyone who wants to improve or broaden their  literary skills, eNotes primary purpose is to serve the needs of high school students and their teachers. Although the Great Books list will broaden the minds of young literary students, many texts have forms of English that are difficult for the modern reader to comprehend. For example, Macbeth by William Shakespeare and The Scarlet Letter by Nathaniel Hawthorne offer fabulous insights and valid moral conflicts but the language is a challenge. Even students who use the plain language version may find it difficult to fully comprehend without an additional study guide (READ: Five Tips for Success in English Class). eNotes offers over 40,000 study guides for books on the Great Books list. Although these can be useful for anyone who wants to improve or broaden their  literary skills, eNotes primary purpose is to serve the needs of high school students and their teachers. Although the Great Books list will broaden the minds of young literary students, many texts have forms of English that are difficult for the modern reader to comprehend. For example, Macbeth by William Shakespeare and The Scarlet Letter by Nathaniel Hawthorne offer fabulous insights and valid moral conflicts but the language is a challenge. Even students who use the plain language version may find it difficult to fully comprehend without an additional study guide. Historical and Contemporary Students who read period pieces such as the Tell Tale Heart by Edgar Allan Poe or Jane Eyre by Charlotte Bronte also benefit from ample background information about the time period and the place of certain characters in society, as well as a complex biography of the author. Contemporary texts can also be an exciting challenge and one of the advantages of eNotes is that it also offers current texts including The Kite Runner by Khaled Hosseini and The Giver by Lois Lowry (CLICK: 100 Best Novels). Accuracy Another advantage of using the study guides on eNotes is the assurance of accuracy. Literature students often Google the text theyre studying and may or may not come across a legitimate source. According to eNotes, the study guides are written by teachers, PhD candidates, and literary scholars. User Friendly Lets say I have been assigned to read 1984 by George Orwell. I can simply click on 1984 and the site will pull up a new page with a summary of the novel. Students are advised to read the summary before reading the full text. eNotes also provides an estimated reading time for each novel to help students manage their study time and understand the complexity of the text. Students who are visual learners can look at the overview on a short YouTube video. Students can also look at a 1984 chapter by chapter summary and analysis, which can be helpful as they prepare for finals. eNotes also provides information about the themes of each text, which is especially important for student reading period pieces of which the themes may appear obtuse. As is common for literary study guides, eNotes also provides a list of primary characters and a summary of their personality or purpose in the novel. In addition, secondary and tertiary characters are listed for reference. While looking through the site for 1984, theres also a list of critical essays which can help students understand how literary critics of the world reviewed this particular novel, or any novel on eNotes, however students should never copy and paste such information to use as their own. For 1984, there are also homework help questions. For example, if a student wants to find out what one of the characters thoughts are on “human heritage and dying” they can do so. Many of the issues that todays high school students have is that a lot of information in period texts asks the reader to ‘read in between the lines’. Sometimes this is simply to make the text more interesting and sometimes it was because the author was not allowed to state outright particular opinions or facts due to the political leanings in the country they lived or in the time they lived (READ: Ask a Private Irvine English Tutor: Writing Apps). Read the Entire Text! Its very important for students to understand that if they only use eNotes they will not receive a passing grade in their class. eNotes, although very helpful, is meant to be a companion to the actual book. Students need to read the full text in its original version or plain language version to fully comprehend the information and do well in their classes.

Math or Magic

Math or Magic Mathematics, the science of numbers, quantities and shapes, is commonly represented as a set of exact rules, formulas and theorems. Math concepts are often hard to understand but they are always based on strong mathematical proofs and justifications. However, even in the accurate world of digits there is always room for astonishing and mysterious facts. There are some math occurrences that look like a magic. Of course, there are mathematical arguments behind each of these riddles but nothing is more magnetic for a vivid human mind than a hint of mystery. Let’s exercise our brains with some of these mystic math puzzles. There is an interesting observation regarding the letter “A”, which is one of the most frequently used letters in the English language. However, this letter very rarely occurs in the names of numbers. From number 0 to 1,000, “A” only appears in 1,000 (one thousand). Isnt that a mystique? Many numbers have magical features. The number 9 is a shining example. If you multiply any number by 9 and then sum up all the individual digits to get a single digit, the sum of all these individual digits will always be 9. There are many other mysterious facts about numbers and sequences of numbers. For instance, 12+3-4+5+67+8+9=100 and there are at least one more expression consisting of nine digits in the right order with math operations between them which results in 100. The result of addition of all numbers from 1 to 100 (1+2+3+4+5++100) is also quite surprising, the total is 5,050. One more form of math magic is the math tricks which allow us to simplify the mathematical operations. For example, there is a fast way to check divisibility of any number by 3. A number is divisible by 3 if the sum of its digits is divisible by 3. Similar smart techniques exist for almost each type of math operations. Mathematical algorithms and thorough calculations are needed to succeed in such venturous activity as the games of chance. However, there is also a great impact on pure chance. So the gamblers are very anxious about various omens and signs. No wonder the gambling attributes are full of mysterious math-related coincidences. Probably that is why the opposite faces of a standard six-sided dice always add up to 7. Due to its abundant sacral background, the number 7 is often considered the lucky winning number. On the contrary, roulette carries a gloomy numerological symbolism. The sum of all the numbers on the roulette wheel is equal to the “Number of the Beast” â€" 666. The mystic meaning of this fact is supported with legends about people who bargained with the devil to catch the secrets of roulette. Science conferred a magic power on the human and enabled us to build the modern world full of high-tech miracles. Mathematics is the queen of sciences and the key to understanding many scientific concepts. There are many small tips and tricks which like the magic spells help to cut the corners on the way to conquering this complicated branch of knowledge. May this force be with you, young student!

Definition of Accuracy

Definition of AccuracyThe accuracy chemistry definition of accuracy is a concept in which something is true, whether good or bad. Therefore, the definition is very important. Often when something is said or done, it has a meaning and thus can be referred to as a truth or it can be a lie.This definition is very important because a person must know if what he or she is saying or doing is true or not. Hence, when one talks about the accuracy of the chemistry definition, it refers to the word accuracy which has many meanings. For example, this definition refers to the frequency of a particular sentence or statement. If it is said in a high frequency or in a low frequency then it can mean that it is true or that it is false.The other definition of the accuracy which is used is the ratio of accuracy. Here, the word 'ratio' refers to the ratio of one part to another. It can also mean the number of parts to the whole. In this case, the word 'ratio' refers to the density or the mass of any su bstance.There are many other definitions of the accuracy, but this is the most commonly used one. If you need to define it in more details, then here are some definitions of the word that you can use: First, the meaning of the word is that the reaction between the reactionants and the product is completely correct.Second, the meaning of the word is that an actual reaction is completely correct. Third, the meaning of the word is that the reaction is complete and so is the product. These are the meaning of the word accuracy and its different uses.Now, you can refer to these definitions in any matter and in any form. This is why it is extremely important to define it properly as this will help you to explain any kind of things clearly.The accuracy chemistry definition is important for one's understanding and application of chemistry. It is very important for professionals and people who are doing research in different aspects of chemistry because they need to know the meaning of the wo rd and use it in their day to day life.
