WebWhy is CP greater than CV explain? Yes, C p is greater than C v because when a gas is heated at constant volume, the work is done only to increase the internal energy of the system. Whereas, when the gas is heated at constant pressure work is done to overcome this pressure and expand in volume and also to increase the internal energy of the system.
