Introduction to Substance Definition in Chemistry

Introduction to Substance Definition in ChemistrySubstance definition in chemistry is the process of determining the chemical composition of the element or substances. This is also known as the procedure of separation, analysis, or quantification. It is a systematic procedure used to define the chemical properties of a specific substance. The term chemical property refers to any physical or chemical property that can be observed, measured, or tasted.There are three types of substance definition: atomic definition, molecule definition, and ionic compounds. Atoms are the smallest particles that include the basic constituents of matter, atoms. Molecules are large molecules consisting of one atom, that contain one to more atoms.Molecules are used to classify and explain chemical properties. Molecular definition is very helpful in defining a substance. Molecules are composed of smaller units that include the basic constituents of matter. These units are collectively called molecules becau se they form the body of matter.Molecules have different chemical properties. For example, carbon is a carbon atom and a hydrogen atom is considered to be a hydrogen atom.Atomic definition is used for describing elements that are stable in a fixed shape, in the form of solid, liquid, or gas. Atomic definition is a measurement used to identify the basic constituents of matter. There are four types of atoms: protons, neutrons, electrons, and nuclei. The smallest atoms have a specific chemical property. This property includes their size, mass, electrical charge, and magnetism.Material definitions are defined by their chemical properties and are useful in chemistry to describe elements, minerals, and minerals that are similar to each other in color, size, weight, shape, melting point, or melting temperature. The composition of metals is another example.Spectrum classification is the measurement used to describe the wavelengths of the electromagnetic radiation which passes through the at mosphere. Spectrum classification is used to determine the chemical compositions of the elements. There are two types of spectra: electric and magnetic.

Movie Restaurants

College Kids Wish They Could Work in These 10 TV/Movie Restaurants Image via commons.wikimedia.org Working in a restaurant may not be the dream of most college kids, but it usually is a reality. Instead of working two dull shifts at your local diner, wouldn’t you rather be working somewhere with a little more character? Though they may not be completely real, there are many fictional establishments that college students prefer over the real thing. Let’s be honest, your usual “What can I get for you today” routine could use some intrigue provided by these television and movie stars. From hilarious hijinks to secrets and adventure, these 10 TV and movie restaurants have everything a college student worker is looking for. 1. Bob’s Burgers (Bob’s Burgers) Tensions may be high while working at Bob’s Burgers, especially with your fierce rival Jimmy’s Pesto Pizzeria right across the street. Every day is a new adventure because you never know what kind of bad luck is going to strike the restaurant next, but at least you always get a good laugh. Plus, you’ll always have the scoop on what weird business has just moved in next door. 2. Krusty Krab (Spongebob Squarepants) Depending on your personality type, the Krusty Krab may be heaven on Earth or the worst place in the world. With frequent break-ins and theft attempts by the wily Plankton, you always have to be on the top of your game. You won’t mind, even if it means losing a few dollars because of stingy Mr. Krabs. 3. Paddy’s Pub (It’s Always Sunny in Philadelphia) If you like working with interesting (if not crazy) co-workers, then you’re bound to love working at Paddy’s Pub. The place may be a bit run down, but you’ll never run out of stories to tell your friends after every shift. It’s hard to believe what The Gang did this week. 4. Inn at the Crossroads (Game of Thrones) Tired of job searching in the North or just need to stop on your journey for some temporary work? Look no further than the Inn at the Crossroads where you’ll hang out with Hot Pie and chow down on some dire wolf bread and kidney pie. Be careful about what you say though, some sketchy characters may pass through. 5. Central Perk (Friends) Working at Central Perk gives you the chance to not only befriend some of the infamous Friends  but also to work with one! Central Perk brings in countless amounts of regulars and even more weird shenanigans. So pour yourself a cup of coffee and get ready! 6. Los Pollos Hermanos (Breaking Bad) Even if the Spanish name isn’t grammatically correct, your time working at Los Pollos Hermanos won’t be time wasted. Just make sure that you turn a blind eye to the sketchy things that go on behind closed doors. You don’t want to get wrapped up in whatever that Walter White is doing. After all, something delicious is always cooking. 7. Monk’s Cafe (Seinfeld) Even if the coffee is crappy and the chef can’t make an egg, you wouldn’t want to miss out on working at Monk’s Cafe. Just think of the interesting characters and conversations that flow through on a regular basis. Who knows? Maybe George will even give you a flirty smile. 8. McLaren’s Pub (How I Met Your Mother) While working at McLaren’s, the drunken regulars may be getting annoying, but at least they’re hilarious. Sometimes they sing on tables, sometimes they get behind the bar, and sometimes they hit on every girl that moves. But hey, word on the street is that the pub makes a pretty good burger. 9. Pizza Planet (Toy Story) Pizza Planet was probably the place of your childhood dreams, even if it was a bit of a challenge for the toys of Toy Story. On your breaks, you can sample the pizza, try your hand at the claw machine, and maybe even drive the famed Pizza Planet truck. What’s better than that? 10. The Winchester (Sean of the Dead) A classic British pub serving up classic British pints makes the Winchester a second home to most patrons. Plus, if you work there, you’ll feel a lot safer just in case, you know, the zombie apocalypse happens. After your shift, you can hang out, have a beer, and wait for the whole thing to blow over. As long as you’re keen to laugh at mishaps and malfunctions, you’re probably a great fit for many of these fictional places. Let’s be honest, with some rather weird customers and even stranger coworkers, you wouldn’t be working there for the wages. You’d be working there for the free entertainment and maybe a few free meals. But whether they’re animated or realistic, funny or daunting, it can’t hurt to imagine what it would be like as a worker in these made-up worlds.

What is an Experimental Section on a Standardized Test

What is an Experimental Section on a Standardized Test Tips from an Orange County Test Prep Tutor: What is an Experimental Section on a Standardized Test? Tips from an Orange County Test Prep Tutor: What is an Experimental Section on a Standardized Test? Students have probably been hearing about the experimental section on many standardized exams, such as the SAT, from their Orange County test prep tutors and classmates. They are likely wondering what an experimental section is and why they have to complete it. Taking a lengthy standardized exam is stressful enough without having an extra part to worry about. Students are right to be curious and should know the ideas behind this type of testing so they can gear their test prep in the right direction. So, what is the experimental section anyway? 1. Reading, writing, or math? On a core subject test, such as the SAT, the experimental section can be reading, writing, or math. Students wont know which section serves as the experimental section, something that makes many test-takers nervous. Students who struggle with writing hope the experimental section will be on this topic in hopes that it won’t count towards their final score, while students who find math challenging expect the experimental section focuses on computation. However, the tests are designed so that students wont have a particular advantage or disadvantage in their composite score (READ: 5 Awesome SAT Apps). 2. Could it be the essay section? No. The experimental section is never an essay section. The essay portion is designed to communicate to universities whether or not a student is a good writer or if they can analyze and argue logically. Because there is only one essay section students can rest assured that this will not be the experimental section. 3. Can I be excused from the experimental section? No. Although it would be nice to opt-out of the experimental section, this is not possible. The point of the experimental section is that students dont know which one it is. Standardized testing companies want students to think the section will count toward their final score so they will try just as hard to do well in that section as they would on any other. If there is an experimental section on a test, it will be mandatory. 4. What is the point of the experimental section? The point of the experimental section is for standardized testing companies to compute an average student score and to make the test harder or easier based on these scores. If the student average gets too low, next years test might be a little bit more natural while if the test seems too easy, next year’s difficulty level will be adjusted. Students take this portion to help testing companies do research on their product. 5. How will it affect my score? The experimental section will not affect the students’ overall score in any way. It’s simply taken out of the exam and used to do research. Essentially, it will be as though the student didnt make that section at all. However, taking an additional section that doesnt count can lead to increased fatigue because the student is investing time and energy in an exam that is taken over multiple hours. Students who are currently suffering from testing fatigue should work with their private Orange County tutor to determine ways to improve concentration and efficiency (READ: Last Minute SAT Study Guide). 6. Who will look at my answers for the experimental section? The testing company will simply take out the experimental section and use it to do research for future versions of the test. Colleges and universities will not see the section nor will they know which questions students answered correctly or incorrectly. Students, educators, and college counselors will also not know which section was experimental. All blog entries, with the exception of guest bloggers, are written by Tutor Nerds.

Why SparkNotes is Killing Your SAT Score - TutorNerds

Why SparkNotes is Killing Your SAT Score - TutorNerds Tips from an Irvine SAT Tutor: SparkNotes is Killing Your SAT Score! Tips from an Irvine SAT Tutor: SparkNotes is Killing Your SAT Score! Many students just love getting out of doing their homework.   In fact, I have found students who have arguably done more work trying to get out of an assignment than they would have if they had just done the original assignment, to begin with.   There is just something about being required to do work that can fire up all sorts of creativity to avoid it (book your private Irvine SAT tutor today. Unfortunately, English classes tend to be the main victims of this trend.   Whether it’s American literature, language arts, and literacy, or reading and writing 101, your English class is guaranteed to include required readings.   The problem with the required readings is that they tend to fit the three main criteria that drive students to skip them: they’re long, they’re boring, and they’re easy to skip without getting in trouble. Now, it is important to note that this isn’t true.   Reading assignments are rarely particularly long unless you procrastinate and have to do it all at once.   The readings usually aren’t uninteresting or academic â€" many teachers strive to assign exciting, interesting, and diverse novels and stories.   And, they aren’t free to skip if you care about your standardized test scores. That’s right, skipping out on doing your required reading will cripple your preparation for tests like the SAT that may determine your ability to get into college.   This is because a key component to your SAT score comes from reading comprehension and critical thinking related to readings.   You are introduced to passages â€" many of which are chosen purposefully for being confusing, boring, or for covering atypical material â€" that you have to read and answer questions about.   The questions assess how well you understood the material, the author’s intentions or opinions, and your ability to draw inferences or interpret messages.   This is also done under a rather strict time limit. As an experienced Irvine SAT tutor as well as a teacher, I can also say that the reading portion of the SAT is often the most difficult for students to improve upon in the short-term (short-term here meaning even as long as a year of studying and preparation).   Your critical reading skills come from years and years of repeated practice and exposure.   A long and thorough history of diverse reading is the best preparation for this kind of test. Dont Avoid Required Reading The problem is, students now often try to avoid that reading.   There are many resources that students use now.   SparkNotes and CliffNotes are the classic examples, but other sites like Shmoop, GradeSaver and BookRags are used.   The main foc,us behind these sites is to give book/chapter summaries of commonly assigned school readings and/or to give quick guides and lists to help students answers common questions.   Students can even take advantage of resources like Quizlet and even Wikipedia and Youtube (check out the channel ThugNotes) for fast summaries to skirt their required readings. These resources are not inherently bad.   In fact, many of them are useful tools to get quick refreshers, prime yourself for future readings, or to efficiently study and remember main points.   The problem is when they are used in lieu of the actual reading.   Without trying to read and interpret the material on your own, you aren’t getting the practice you need to have high quality comprehension skills.   If you are letting SparkNotes tell you what everything means, then you are missing out on the learning opportunity of figuring it out on your own. Many students complain that they don’t understand some of the required readings that they are assigned.   That if they didn’t read summaries and shortcuts that they would fail their assignments because they can’t understand what’s happening in the book.   This is okay!   The act of struggling through a reading and not being comprehending everything is how you get exposed to new writing and get better at reading it.   This is where you can use these resources and it is how most of them are meant to be used.   Do your reading, then refer to a guide to help you piece together any parts that you struggled to grasp. If your M.O. in English class has been to never open the book while you skate by with quick and easy summaries, then you are not alone among students everywhere.   But you should know that by doing so you are taking away your main source, of reading comprehension and critical verbal thinking practice.   Take the time and always try your readings â€" your SAT score will thank you.
