In an isobaric process (`lambda` is adiabatic exponent of the gas)

One mole of an ideal gas is carried through a thermodynamics cycle as shown in the figure. The cycle consists of an isochoric, an isothermal and an adiabatic process. Find the adiabatic exponent of the gas.

Find the molar heat capacity of an ideak gas in a polytropic process p V^n = const if the adiabatic exponent of the gas is equal to gamma . At what values of the polytropic constant n will the heat capacity of the gas be negative ?

Adiabatic exponent of a gas is equal to

Adiabatic exponent of a gas is equal to
