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

(D) The entropy in the process does not change
Correct option (A) The process is adiabatic
Explanation:
In sudden expansion gas do not get enough time for exchange of heat.
∴ Process is adiabatic.
