Heat capacity (Cp) is an extensive property but specific heat (c) is an intensive property. What will be the relation between Cpand c for 1 mol of water?

o Heat capacity (Cp) of a substance is the amount of heat energy required in order to raise its temperature by 1 Kor 1 oC.


o Whereas, The specific heat is the amount of heat per mole required to raise the temperature by one degree.


1 mole of water = 18 g.


Hence, for water Heat capacity = 18 × specific heat.


i.e. Cp = 18 × C .
