An ideal gas of mass m is contained in a rigid tank of volume V at a pressure P. During a reversible process its pressure reduces to P1 . Following statements are made regarding the process.
(P) Heat is transferred from the gas.
(Q) Work done by the gas is zero.
(R) Entropy of the gas remains constant.
(S) Entropy of the gas decreases.
Among the above statements, the correct ones are
  • a)
    P and R only
  • b)
    P, Q and R only
  • c)
    Q and R only
  • d)
    P, Q and S only
Correct answer is option 'D'. Can you explain this answer?

At constant volume to decrease pressure, temperature has to be decreased. So heat has to be transferred from the gas.
As the change in volume is zero, work done by the gas is zero. Entropy of the gas decrease as system is losing heat.
