The temperature of an ideal gas having constant specific heats is given as a function of specific entropy and specific volume as T(s,v) = Av1-k exp(s/cv) where A is a constant. For a reversible, constant volume process, find the expression for heat transfer per unit mass as a function of cv and T using Q = ∫TdS. Compare this result with that obtained by applying the first law to a closed system undergoing a constant volume process.
