Work done by adiabatic expansion derivation
I know that $W=-C_v(T_2-T_1)$ for an adiabatic expansion, and I know how to derive it. However, in this video (https://youtu.be/gaZmZjBtgAM?si=Px3v2qDG3CIdupgi&t=358) it mentions the formula $W=-\...

A problem on adiabatic process [closed]
I solved this using the relation PV^gamma = constant (since it's an adiabatic process) and solved for the ratio of volumes. The answer key has, however, proceeded with delta U + delta Q = 0. The ...

Question regarding adiabatic process (Ex 12.2 in Blundell's Concepts in Thermal Physics)
It can be derived from first law of thermodynamics that
$$dQ=\bigg(\frac{\partial U}{\partial T}\bigg)_V dT +\bigg[\bigg(\frac{\partial U}{\partial V}\bigg)_T+p\bigg]dV$$
On page 119 of the book, a ...

Adiabatic Invariance and Magnetic Moment
In plasma physics, particularly, in magnetic mirrors, we have a very well-known result, which is the invariance of the magnetic moment of the particles trapped in the mirror.
I've saw in some notes ...
