Passage

Read the passage given below and answer the questions that follows:

A diathermic piston divides adiabatic cylinder of volume V 0 into two equal parts as shown in the figure. Both parts contain ideal monoatomic gases. The initial pressure and temperature of gas in left compartment are P 0 and T 0 while that in right compartment are 2P 0 and 2T 0. Initially the piston is kept fixed and the system is allowed to acquire a state of thermal equilibrium.

Diathermic piston divides into adiabatic cylinder.

Diathermic Piston Divides Into Adiabatic Cylinder.

In above figure we show that a diathermic piston divides adiabatic cylinder of volume V0 into two equal parts
