A gas at initial temperature T undergoes...

A gas at initial temperature T undergoes sudden expansion from volume V to 2V. Then -

A

The process is adiabatic

B

The process is isothermal

C

The work done in this process is nRT `"In"_e` (2) where n is the number of moles of the gas

D

The entropy in the process does not change

Text Solution

Verified by Experts

The correct Answer is:
A
For a sudden expansion `Delta theta = 0` so the process is adiabatic.
