the energy required for a particular change in temperature is given by the specific heat capacity. the energy required for a particular change in state is given by the specific latent heat.
Specific heat is the amount of energy (in Joules) that is needed to raise the temperature of a substance by one degree Celsius. ... Water's high specific heat is very useful to life. If water did not have such a high heat capacity, the temperature of Earth would change violently with the changing of day to night.
The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1°C.
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we'll refer to as simply "heat capacity", meaning it takes more energy to increase the temperature of water compared to other substances.

The specific heat of gas at constant volume in terms of degree of freedom 'f' is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. Monoatomic gas has only one translational motion, hence three translational degrees of freedom.
