Kinetic Molecular Theory and the Ideal Gas Laws

[@danielmejorado6098]

I like the calm and concise delivery. No zany personality, no senseless entertainment gimmick. Just a solid breakdown of what, how, and why. Gracias.

[@aadithyahrudhay2269]

Better than Crash Course, if I may. Less drama, more facts delivered in a calm and composed manner.

[@AS-mm4pn]

I love both of these channels.Yeah there is much drama by Hank but information and its explanation isn't a dumb one because of that.

You dont have to put down something just to appreciate some other thing! Professor Dave is awesome and so is Hank Green. They both have different styles of teaching. Prof. Dave teaches in a calm & composite manner. Hank teaches in a more fun & hands-on kinda manner. And I think both are amazing in their own unique ways.

[@FriminaFaustine]

That's alot you explained really nice and you made me understand without any hesitation.

[@PentameronSV]

3:23 I still don't understand how the gas constant works. EDIT 1: I mistakenly thought that 'R' equals '0.0821 multiplied by whatever fraction shown on the right'. Am I correct in saying that the fraction at the end of the equation symbolises the many units for the number '0.0821'? Like, for example, the user can freely choose to use the unit 'L', making 'R = 0.0821L'? EDIT 2: Okay, I get it now. At 4:29, in the longest equation under the second question, the aforementioned units are necessary for the other units to cancel out in both the numerator and denominator of the fraction. To quote Professor Dave himself at 3:26, the gas constant (R) "makes these calculations intelligible in our man-made units."

As a planetary astronomer dealing with atmospheres, I'm much more comfortable using SI units, a weird unit we thought up for atmosphere chemistry called the kilomole (1 kmol = 1,000 mol), and an appropriately adjusted SI value of R (8,314.4598 J K^-1 kmol^-1). But I suppose if I had to deal with amounts of gas that could fit in vessels and tubes in a chem lab, I'd use the units you use here!😁

Can you please check am I right ( my answers are 1,3,4): For an ideal gas which of the following statements are correct: 1. Increasing the temperature of a gas at a constant pressure increases its volume 2. Increasing the pressure of a gas at a constant temperature increases its volume 3.Increasing the temperature of a gas at constant volume increases its pressure 4.At the same temperature and pressure one mole of helium gas occupies the same volume of one mole of argon gas 5.The ideal gas law applies only to monoatomic gases. thank you :-)

Hey guys, I wanted to ask you something. I’m a foreign student and in my country we don’t use decimal numbers much. Instead, near whole numbers are given in the questions. therefore, we don’t need nor use calculators while solving questions. Given these circumstances, I realized I don’t really know how to do these calculations 🫠 I was wondering if the calculations in checking comprehension part require a calculator, or am I expected to be able to do the calculations without it? It’d be greatly appreciated if you could answer me 🫶🏻

Why if you use the ideal gas law you get 13L and if you just use volume and moles (22,4 × 0.785) ÷ 1 = 17,6L?

[@livingfaithsuan5084]

Oskar Olszewski i don’t know if this could help but maybe bc the problem is not at STP? So maybe it’s not acceptable to assume that the volume and mole is 22.4L and 1mol, initially

[@malakmohammed2460]

sooooooooo amazing explanation!!!!!!!!!!

[@gabriels2395]

Hi Professor! Thank you so much for your videos!!. I have a question. Is it possible to *increase the pressure* and at the same time *not to increase the temperature* as a result of this? I think about the diesel motors (for example) that use high pressure for diesel to ignite within the piston and cause the explosion, which I think is because the increase in pressure *heats* the diesel enough as for this to explode (the increase in pressure increases, *consequently,* the temperature).

[@ProfessorDaveExplains]

sure one can definitely keep temperature constant! compression will not always be accompanied by temperature increase. this is called an isothermal process.

[@gabriels2395]

thank you for replying professor! This is a bit counterintuitive to me though. I found something on Wikipedia _en.wikipedia.org/wiki/Isothermal_process_ _...Doing work on the gas increases the internal energy and will tend_ _to increase the temperature..._ it says (to me) that the increase in pressure increases the internal energy, which needs to leave the system for the temperature not to change (going to the environment as heat). So there is an increase in temperature just that the system makes up for this by releasing such heat. Is there any instance in which increase in pressure would not make us deal with heat production (for us not even to need to get rid of any produced heat?)

[@ProfessorDaveExplains]

yes that would be an adiabatic process! and in fact, boyle's law talks about pressure and volume changing with temperature remaining constant. so it's just about tweaking the parameters.

OK profesor!! Thank you for replying!
