Temperature and Kinetic Theory

Prerequisite: chemistry

My regular physics class actually did not cover any thermal physics because most were covered in chemistry. Even so, my regular chemistry teacher was *cough cough* so I learned most stuff from AP chemistry. Here are the stuff I have left to gleam, which are mostly just equations. They are not particularly important in AP, but they are good to know~

When change in temperature causes change in length or volume. Can be written in the format on the right.


Thermal stress is a form of pressure. This is not likely to appear in AP as Young's modulus is not covered. Whatever that is. It has something to do with elasticity.



Here is another form of PV = nRT. Despite this, the classic nR form is still more common in AP than this Nk form.


I came across this vaguely in AP chemistry. Now it is a lot more clear. Geez, why did the textbook not put it this way:



where k is Boltzmann's constant.

More stuff. Nice to know, but not vital.



Also nice to know. The final answer can be in any (mass / time) unit depending on what you use in your substitution.



That symbol J.. physicists are really running out of alphabets to use! They finished the Greek letters, might as well use Chinese characters next. Sure, we have plenty of Chinese characters~

Next in the thermal physics trilogy is Heat
