WebThe relationship between C P and C V for an Ideal Gas. From the equation q = n C ∆T, we can say: At constant pressure P, we have. qP = n CP∆T. This value is equal to the change in enthalpy, that is, qP = n CP∆T = ∆H. Similarly, at constant volume V, we have. qV = n CV∆T. This value is equal to the change in internal energy, that is,
