WebMay 13, 2024 · S2 - S1 = Cp * ln ( T2 / T1) - R * ln ( p2 / p1) where Cv is the heat capacity at constant volume, Cp is the heat capacity at constant pressure, and ln is the symbol for the logarithmic function . If we divide … WebApr 5, 2024 · CP is higher than CV because when the gas is heated at constant volume, no external work is done and the heat supplied is consumed only by increasing the internal energy of the gas. Yet if the gas is heated at constant pressure, the gas will expand against the external pressure, and some additional work will be performed.
