Heat capacity (C) is the measurable physical quantity that characterizes the amount of heat required to change the temperature of substance by a given amount.

The amount of heat required to raise the temperature of one mole of a substance by one degree Celsius or Kelvin is called molar heat capacity(Cm)

The amount of heat required to raise the temperature of unit mass of a substance by one degree Celsius or one Kelvin is called specific heat capacity.
