45. The value of Cp is greater than C, for an ideal gases, because (a) They are just two different quantities with no relationship between them. (b) For Cp, a part of heat entering the system is used up by doing work on the environment, hence more heat is needed to cause increase of temperature. (c) For Cv, gas molecules have a smaller kinetic energy since volume is constant, therefore less heat is required to cause an increase in their temperature. (d) For Cv, volume is constant, so less heat will leak out from the system, and therefore less heat is required to increase gas's temperature.
