Heat transfer in the Carnot cycle occurs at zero temperature differential, an impossibility in the real world. WebAnswer (1 of 3): Because they give the maximum amount of work for a given amount of heat. A gases' internal energy depends on it's temperature. In isothermal process, gases' temperature is constant. That means, no energy is wasted in increasing the internal energy of gases. Therefore whatever he...
