A gas at initial temperature T undergoes sudden expansion from volume

1.	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 nRTlne(2) where n is the number of moles of the gas.(D) The entropy in the process does not change
Answer» Correct option (A) The process is adiabatic Explanation: In sudden expansion gas do not get enough time for exchange of heat. ∴ Process is adiabatic.

Answer»

Correct option (A) The process is adiabatic

Explanation:

In sudden expansion gas do not get enough time for exchange of heat.

∴ Process is adiabatic.
