I'm no expert but I think there's a slight problem with the explanation of the temperature increasing the volume. In the example, the gas was in a balloon (called a container) and it was said that increasing the temperature means making the molecules move faster, thus pushing out the container.
However, it was stated earlier that one of the assumptions of an ideal gas is that its volume is much less than that of the container. This raises the question, are we talking about the volume of the gas, or of the container?

Your concept and materials are strong. but videos are going too fast to understand even at 0. 75-speed.
Thanks for providing us so much knowledge and concepts used in daily life. which matters and also important.
But kindly make the complete videos on these topics so that we will understand even more from it
And it helps a learning student a lot.
Thanks again

SECOND QUESTION. So, in the final example, if the car _was_ airtight, would that mean that the temperature inside couldn't change? That can't be right can it- the radiation should still give energy to the molecules inside. So then, does the constraint of Pinside = Poutside no longer hold true? Or, would the volume expand?

How can the pressure remain constant with an increase in pressure in the car analogy given at the end? And how can number of moles of gas change in the airtight car?
Sorry if I'm being dumb, and thanks in advance: )

great job with the colorcoding of the variables, great job explaining everything and also great work doing a short video with A LOT of content. wins a sub in need for more.

crazy thing about temperature: a single particle can not have a temperature, there needs to be multiple particles/molecules/things moving around and bumping into eachother

It contracts in cooler weather so the metal thing in the bridge gets further so it will fall appart because it's going further apart so the bridge will fall

lol I went to Google maps to see if these expansion gaps exist, and I then found that I am continuing to watch the video a few weeks later.

You talked about ideal gases without even mentioning Boltzmann.
Did you ever hear the tragedy of Ludwig Boltzmann the wise.
