Be Lazy! Don't Memorize the Gas Laws!

To see all my Chemistry videos, check out
socratic.org/ch...
Here is a really fantastic shortcut you can use so you don't have to memorize any of these gas law: Boyle's Law, Charles' Law, Gay-Lussac's Law, Avogadro's Law, and the Combined Gas Law

Why couldn't my teacher just use tylers videos as lecture? first chem test i took read the chapter, did all the practice problems and read the slides, made a 75 and almost made me drop the class. 2nd test all i did was skim the slides and watch tylers videos and i got a 98. Teacher literally accused me of cheating, but once i showed her ur explanations her mind was blown and now she suggests u to all her students.

[@theelementofminecraf]

[@jjzellers]

It might be better to explain that when you move the variables that you need to the left side of the equation, the variables on the right side are all ones that are not changing. So, for example if you are given a problem with an initial temperature and pressure, and are asked for what the pressure is if the temperature changes, the number of molecules (n), the gas constant (R) and the volume (V) are all constant. Or in other words P1/T1 = nr/V = T2/T2.

[@hiraimochi6946]

I have an exam in a few hours, and this really helped me a lot! What a lifesaver...

[@gurkyboss]

You sir are a genius. I've got a Chem exam tomorrow and I was finding it difficult to remember 5 difrent formulas. Rock on!

[@tdewitt451]

yeah, that can work, but not if you want to find the number of moles, like in avogadro's law for example. there are certainly many ways to remember this; the method i talk about here is just one. do whatever works for you!

[@tdewitt451]

you get rid of it, because you don't need it. remember: you're not solving PV=nRT, you're just using it for a trick to be able to get any gas law you need. so don't worry about getting rid of parts of the equation. you just get what you need on one side, get rid of everything else, and then double what you need on the other side of the equation, and you're done--that's your new equation.

[@DegenerateOppaiFan]

Tyler I just wanna say, you are amazing. This one video just gave me so much confidence and peace about this chapter and formulas, thanks man I instantly subscribed, your other videos have helped me too, I will be around for awhile and will share this with others who need help, thanks again man and please keep it up you are making a difference in people's lives, not everyone wills ay it, but there are probably so many more like myself and other commentators who breathed a huge sigh of relief after your help, thanks again

[@victoriacarlson201]

Tyler you are heaven sent. I'm taking a condensed Chem-120 class in college and I may be overly dramatic... but I have cried over this class. My professor, while a wonderful person, just is not clear enough in lecture and I leave more confused than I go in. However, your videos have completely changed my view of chemistry. You make it make sense! You have saved me so much time, energy, and tears because you are such a clear, concise, and passionate teacher. I sincerely thank you so much for making videos like this.

[@elizabethdelarosa8166]

this helped so much !!! everything my chemistry teacher says just sounds really abstract and she's not the best at teaching because she often skips a few steps and makes us memorize a lot of stuff, like these laws. but this really helped and makes me less stressed about the test I have on it tomorrow !

Thank you for doing this. My chemistry teacher in tenth grade did this and said what you did and magically derived the gas laws from the Ideal.

[@Idk-bs6in]

I watched all his law gas videos, and understanding what I'm doing is much easier, and I actually understand the situation when doing it, and also know the variables are constant, if the problem doesn't tell you, our professor also sort of said the same thing, but didn't explain it as in depth, but I had already watched all these videos and so understood him.

Gracias Tyler. its 2019 and you saved me from my semestral exam tomorrow!!!

[@towhichenddrops1912]

You should really consider making a calculus series. You’re style would make it a breeze to learn since I’ve noticed you just slip in pointing basic algebra or calc that people may have just forgotten and most profs just ignore like everyone is on the same page.

[@marykling2120]

I teach high school chemistry. Tyler does a very good job with his videos. I often use them. These assume that students are able to manipulate equations. If students don't have a strong foundation in algebra (which they should have) this video isn't helpful.

[@mperkinz22]

TYLER YOU’RE THE BEST!! BEEN WATCHING YOUR VIDEOS SINCE I WAS IN HIGH SCHOOL AND NOW FOR MY LICENSURE EXAMS 🥺

[@13IsMyLuckiestNumber]

If you cancel out the pressures in (P1xV1)/T1 = (P2xV2)/T2, then you'll be left with V1/T1 = V2/T2. charles law is V1/T1 = V2/T2. What you said, V1xT2 = V2xT1, is the same as V1/T1 = V2/T2; just rearranged differently. hope this helped :)

At the beginning of the semester, my prof. told us not to watch youtube videos for chemistry because the information would be wrong. So, I worked my butt off, stressed, cried, and struggled to earn a decent grade. Fast forward to today, the day of my final and I start watching these videos to review the information I learned the hard way, and not only is the information correct, but it is SO SIMPLE.

The Ideal Gas Equation (expressions) may be derived simply by studying the fact that multiplying by one is symmetric in yield to adding zero. There are implications that all chemistry noted within The Standard Model of Particle Physics are halogen derivative. Makes sense imo as it is in keeping with the nomenclature of halogens.

I usually just do P1xV1/T1=P2xV2/T2 And find out the constant. Then I cross out the constant in the equation above. Then I have the equation I need for the problem. :)

[@marulane7159]

Whenever i ask my chem teacher to teach mr the problems again cuz i dont quiet get it she suddenly laughs like a maniac and tells me that shes already taught it in class already before and by now i shouldve known how to solve it.

I wish i could like this video two times,your the best chemistry teacher,before i use to hate chemistry because all the teacher make it look so hard.after finding you on youtube i can't believe these are what i couldn't understand,your really good trust mi,this short cut to the gas law should be call your law

The mathematical explanation to removing nR/V in the beginning is that the variables in nR/V (n, R and V) are all unchanged. The only thing that was changed was the pressure (p) and the temperature (T) You can say that you must compensate for the change in the individual variable of p or T, so that the value of the expression p/T stays the same. So if p/T is the same at all times, p1/T1=p2/T2 is true. (After 30 minutes of trying to get it simple I see why you left that out.)

[@SuperVapourizer]

Maybe you should mention that the variables on the right of the equation have to be constant otherwise you cannot say that, e.g. p1*V1=p2*V2. Don't know wether that is obvious for everyone... Best Regards

[@sidewaysfcs0718]

alternatively, if you want to spare some more time , you can just add "dummy-vallues" to the things you don't need, like volume and moles in this case. setting volume to 1 L, and moles to 1 mole, would produce the same results as just using the Gay-Lussac Law. actually, it doesn't even matter what dummy values you use, but 1 is an easy number to pass by.

[@carultch]

Some teachers will mark you wrong for assuming an arbitrary value of terms that will ultimately cancel out of the equation. Often times, part of the scope of the assignment is to show that your solution is independent of the variables you were not given, rather than just to get the right answer.
