Temperature and Average kinetic energy of moleces

AI Thread Summary
The discussion centers on how the temperature of air is affected by the addition or removal of hydrogen molecules based on their speed relative to 1980 m/s. Adding a hydrogen molecule with a speed higher than 1980 m/s will increase the temperature, while removing one with the same speed will decrease it. Conversely, removing a hydrogen molecule with a speed lower than 1980 m/s will increase the temperature, and adding one with a lower speed will decrease it. The assumption that the average speed of all molecules is 1980 m/s is crucial for determining the temperature changes accurately. Clarifying this assumption is essential for understanding the overall impact on temperature.

Is the assumption here that the average speed of all the molecules is 1980 m s/-1? Because if it is not, the answers could be anyone's guess.

Also, what do you think the answer should be?

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
