The heat required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature. Γ is defined as ratio of heat capacity at constant pressure to heat capacity at constant Molar heat capacity is defined as the energy required to raise the temperature of one mole of Ideal gas by one Kelvin at constant volume. If f is degree of freedom of Ideal gas, then from equi-partition law of energy, the total sum of energy is equivalent to sum of kinetic energy associated with each degree of freedom The specific heat of a material is numerically equal to quantity of heat required to raise the temperature of unit mass of that materials through 1 unit ![]() Heat capacity of a body is numerically equal to quantity of heat required to raise its temperature by 1 unit There are different parameter which is helpful to determine Heat exchange of system mainly comprises Fluid and Gas. When two systems with different temperatures are put in contact, heat flows spontaneously from the hotter to the colder system.
