Specific heat is the amount of heat required to raise the temperature of the substance by one degree.
The amount of heat required to raise the temperature of a gas at constant pressure is different from that at constant volume. The specific heat at constant pressure is greater than that at constant volume. This is because, in case of constant pressure, the heat supplied is not only used to increase the temperature of the gas, but also for increasing its volume.
specific heat capacity is the heat required to raise the temperature of 1 kg of a substance through 1k or 1.C
