Molar heat capacity


The Molar Heat Capacity of a system is defined as “the amount of heat required to raise the temperature of 1 mole of the substance through 1oC.”
                Molar Heat Capacity is denoted by C. The molar heat capacity C varies with temperature and its value will be given as;
                                C =  dq/dT
                Where dq is small change in heat and dT in temperature.
Units
            The units of Molar Heat Capacity are calories per degree per mole or in S. I. units Joules / degree / mole (JK–1mol–1).
