For an isochoric process,(adsbygoogle = window.adsbygoogle || []).push({});

dV = 0

therefore dW=0

So from 1st of Thermodynamics,

dQ = dU + 0

or, n*Cp*dT = n*Cv*dT (Cp and Cv denote molar heat capacities of the gas at const pressure and volume resp.)

therefore we get Cp = Cv .(how can this be possible once we know Cp - Cv = R ?)
