i he initial pressure and volume of a given mass of an ideal gas (with‌

Cp

Cv

=γ), taken in a cylinder fitted with a piston, are P0 and V0 respectively. At this stage the gas has the same temperature as that of the surrounding medium which is T0 . Itis adiabatically compressed to a volume equal to

V0

2

. Subsequently the gas is allowed to come to thermal equilibrium with the surroundings. What is the heat released to the surroundings ?
