Two identical thermally insulated vessels interconnected by a tube with a valve contain one mole of the same ideal gas each. The gas temperature in one vessel is equal to `T_1` and in the other, `T_2`. The molar heat capacity of the gas of constant volume equals `C_v`. the valve having been opened, the gas comes to a new equilibrium state. Find the entropy increment `Delta S` of the gas. Demonstrate that `Delta S gt 0`.
