प्रश्न
Explain why the specific heat capacity at constant pressure is greater than the specific heat capacity at constant volume.
Advertisements
उत्तर
It implies that to increase the temperature of the gas at constant volume requires less heat than increasing the temperature of the gas at constant pressure. In other words, s is always greater than sv.
