Why Are Numbers Used in Chemistry Often Expressed As Units of Measurement?

Why Are Numbers Used in Chemistry Often Expressed As Units of Measurement?We all know why numbers are used in chemistry often expressed as the units of measurement of energy, mass, and time. But what other units are commonly used?In different laboratories, you may find that different laboratories use different units of measure. Let's take the simplest example, that of the strength of water. You may find that you use the metric system, which is a standardization system that allows for comparison between the measurements that scientists make in different laboratories. To compare, you may compare water that is derived from a nearby creek.To measure the strength of water, you would measure the water density, then you would convert the weight of the water to kilograms and finally, multiply the mass of the water by the density. The formula for this is:Since water is so dense, the density of the water is greater than that of the surrounding water. The density of the water weighs more than t he density of the creek. Thus, this means that the strength of the water is greater than the strength of the creek.Another example of strength may be in chemicals. You may find that the chemical is not volatile or semi-volatile. In fact, the chemical is volatile and non-volatile. Some molecules have properties that cause them to be mixed and re-combined, creating another compound, which may be volatile, semi-volatile, or liquid.To be able to determine whether a chemical is volatile or non-volatile, you may need to know the valence of the chemical. When you first get to a laboratory, you may find that the compounds are not properly labeled, and you need to go to a chemist to label the compounds before you can try to make the chemicals. This is when the solubility or quanity of the chemicals comes into play.You may find that certain measurements are needed to make certain measurements. Once you understand how the units work, it can help you make better decisions.

Allergies in the back to school season. - ALOHA Mind Math

Allergies in the back to school season. CT State Department of Education school health consultant Stephanie Knutson talks in this article about how parents need to work with the school to create a safe environment for children with food allergies. This is not the only type of allergy to be concerned about, and here are a few ways in which parents can deal with kids who are susceptible to allergies going back to school in this season: Food Allergies: If your child suffers from an allergic reaction to specific types of food, you need to make sure that this information is available in her health records, as well as communicate with her teachers in school personally if possible. In case of children eating at school, the food preparation needs to take this into consideration and avoid common allergy causing ingredients, or if not avoid, label them. The above-mentioned article also mentions that you must authorize the school to use emergency medication such as an epi-pen after consulting with your pediatrician. Breathing and Ast hmatic Allergies:Make sure that your child has the necessary medication at hand for an emergency situation. Write a note to the teacher specifying what sort of situations might trigger the allergy â€" such as excessive exercise, exposure to pets, to chalk dust, or to the dust in the playground. In this way, someone at school will be alert in case they see the child feeling uncomfortable in any of these situations. Kids and allergiesImage Courtesy:http://www.freedigitalphotos.net Nasal Allergies: Some conditions like allergic rhinitis or hay fever may not lead to high-alarm situations, but can still cause a child a lot of discomfort. It would be ideal if the child takes their medication before going to school, for relief during the day. Do inform the teacher and nurse, if you think any specific allergens need to be avoided. Allergy to bites: Some children may have a severe reaction to insect bites or stings, and similar to the food allergies you need to make sure that the school has some injectable epinephrine that can be used in emergency situations. Discuss with the teachers and the school nurse regarding the procedure that would be followed in such a situation. It is definitely possible to work with the school authorities to make it easier for your child to handle any allergies while at school. While physical allergies can be difficult to deal with, when addressing the aptitude for studying and levels of concentration of your child, we at Aloha USA can hel p to focus and improve the same.

Thanksgiving and Politics at the Table

Thanksgiving and Politics at the Table Photo Via: Pixabay.com 1. Avoid Getting Heated One of the biggest mistakes that individuals make when at the Thanksgiving dinner table and discussing politics is to get a little too heated in the midst of the arguments. Avoid this issue at all costs! Getting heated typically leads to arguments that you can’t take back, and it’s going to make the day more awkward than it is fun. For this reason, simply avoid getting heated and, if you feel that you’re too passionate about an issue, stay quiet and think about something else. 2. Steer the Conversation Elsewhere You’ll likely end up having to steer the conversation elsewhere several times throughout the day. In some instances, you may not be involved, but you will notice that the family members that are feel far too passionately and they aren’t going to agree. When this happens, make sure you steer the conversation elsewhere, avoiding issues where you can. Throw out some fun anecdotes from your time at school, or perhaps even distract them with other, lighter news. Whatever you can do to stop the argument and steer the conversation somewhere else will definitely be in your best interest. 3. Stick to the Facts Another error that individuals make when sitting at the Thanksgiving table and discussing politics is that they won’t stick to the facts. When you’re discussing politics, it’s important that you are informed and speaking without getting to an emotional level. Only interject when you feel that you can keep a level head, and when you’re sure that you can stick to the facts. If you know that you’re too passionate about a topic, or that you aren’t informed enough to comment, make sure you don’t contribute to that conversation. Again, it sounds like common sense, but in the heat of the moment, it’s easy to throw out unfounded information. 4. Know Your Audience There are some arguments that just aren’t worth having, and more often than not, politics at the family dinner table is one of those times that you’ll want to avoid an argument. If you know that your family members are on one side of the political spectrum and you are on the complete opposite, it’s not worth attempting to have a conversation. If you think about it, it’s so important to know your audience, as there are some individuals that you will never be able to win over, and others that are more open to your side of an argument. If you know a family member isn’t that type of person, don’t push the conversation! 5. Keep Things Light A little levity can go a long way during some heated, political debates. For this reason, throw out some jokes (when appropriately timed) or some more light-hearted conversation starters to move the conversation to something a little more fun. Thanksgiving doesn’t have to end in a fight every year, and by keeping things light, you’re far more likely to walk away with your familial relationships still intact. 6. Walk Away Last, but definitely not least, there is always the option to simply walk away from the conversation. Sometimes, politics can be a bit too much, and if you’re not in agreement with any of the items being discussed at the table, you’re always welcome to remove yourself from the situation. Excuse yourself to walk to the bathroom or to grab another drink from the kitchen. Just taking a few minutes away from the table to compose yourself will certainly help you to keep your head this Thanksgiving. Just remember that not all conversations (especially when they involve politics) will be your cup of tea, so give yourself an out when you need it! Again, Thanksgiving doesn’t have to be a battleground between you and your family members. Rather than falling victim to the faux pas of discussing politics at the dinner table, make sure you are prepared to avoid arguments, by any means necessary. The above six steps are a great starting point, but, when in doubt, just walk away and ensure you have a Happy Thanksgiving. That way, you’ll be able to sit back, relax and enjoy that Thanksgiving turkey that you’ve waiting for since last November. Have a Happy Thanksgiving everyone! And good luck avoiding the politics!

Practical Tips for Your First Physics Class - Part 1

Practical Tips for Your First Physics Class - Part 1 Tips from a Private Irvine Physics Tutor: Practical Tips For Your First Physics Class Tips from a Private Irvine Physics Tutor: Practical Tips For Your First Physics Class The internet is full of tips and tactics from bloggers, tutors, and teachers about how to excel in physics. Unfortunately, the predominant advice is the ever-prevalent generic comments that students have been hearing about every class in every subject for years: “go to class,” “do your homework,” “do extra practice problems,” “take good notes,” etc. If you’re lucky, your basic physics tips might also include some points about being good at math and trying to understand the concepts instead of just memorizing book your private Irvine physics tutor. You already know these things. These tips are continuously repeated and are not helping you better prepare for or succeed at physics. Here, we will cover six specific and practical tips that can help you get through your first physics class, whether it’s high school, AP, or college. 1. Be an expert at formula manipulation Formula manipulation is typically an algebra 2 concept where you have an equation with multiple variables that you can alter to solve for specific variables or plug-in specific values. For example, the volume of a pyramid is V = 1/3 A H where A is the area of the base and H is the height of the pyramid. However, we can manipulate this equation to instead give us height instead of volume by dividing both sides by A and multiplying by 3: H = 3 V A This skill is essential in physics where you constantly move variables from one side of an equation to another and substitute numbers and variable for other variables. In our pyramid example, we might have to substitute in an area equation to find the height: A = L W where L is length and W is width. This could give us the new height equation: H â€" 3 V L W If this example did not seem very easy to you, you need to go back and practice a lot of these types of problems. Take equations with many variables and practice isolating each individual variable one at a time. 2. Be an expert at basic trigonometry Your physics class likely won’t require you to know all of the identities and properties of trig functions that you may have learned/are learning in your precalc or trigonometry class, but you do need to be very good at your simple sine, cosine, and tangent definitions with right triangles, as well as the Pythagorean theorem. Don’t forget your SOH-CAH-TOA, make sure you can do a2+b2=c2 in your sleep, and practice finding missing angles and sides of right triangles even when they’re upside down or inside out. Basic trig is vital for early vector problems. It is also common to break diagonal lines into their x and y “components.” Don’t fall for it if someone tells you to “just use sine” “or just take the cosine” when you’re doing these problems. Draw the triangle and figure out why you’re using that trig function. It will save you when the problems get harder later. 3. Know your units 90% or more of your physics work will revolve around only three basic units: the kilogram (kg) for mass, the meter (m) for length/distance, and the second (s) for time. You can break up almost everything you do into just these three simple components. The unit for speed is m/s. Think miles per hour translated to meters per second instead. Being an expert with your units can help your understanding of the equations and help you check your answers. For example, a basic physics equation is the definition of force: F = M A where M is the mass of an object and A is its acceleration. The unit for mass is the kilogram, and acceleration is meters per second squared. Multiplying these we get kg*m/s2. In class, they will call the unit of force a Newton, but we now know that a Newton is just a kg*m/s2. When you hear new units like the Hertz, the Joule, or the Pascal, remember that you can break them up into these basic parts. This can help a lot with topics like conservation of energy. (Note that the units for temperature, Kelvin (K); current, ampere (A); and amount, mole (mol) are also fundamental units that are used to a much smaller extent in physics 101). The first three tips can help you prepare for physics and understand what’s going on. You will be very confused if you don’t know your triangles and basic trigonometry. You’ll also be very behind if you can’t quickly modify equations and substitute variables. Finally, understanding the units and their basic components can set you up to actually understand some of what you’re doing when you do examples.
