An isolated box is partitioned into two compartments, each containing an ideal gas of different molecular species. Assume that each compartment has the same temperature, but different no. of moles, different pressure, and different volume. The partition is suddenly removed and the system is allowed to reach equilibrium. a) What are the final temperature and pressure? b)What is the change in entropy?
Attempt:
a) The temperature still remains the same. I assumed that energy of the system equals the energy of individual compartment. On equating, I got the same temperature. For pressure, I used $PV=nRT$ where temperature is still the same. b) Since, initial and final temperature are same, I assumed that there is no change in entropy.
I would like to know if it correct or not? Thank you for any help :)
