Answer»

Heat capacity of the body is the amount of heat required to raise the temperature of (whole) body by 1 ℃whereas specific heat capacity is the amount of heat required to raise the temperature of unit mass of the body by 1 ℃.

Heat capacity of a substance depends upon the material and mass of the body. Specific heatcapacity of a substance does not depend on the mass of the body.

S.I. unit of heat capacity is JK-1 and S.I. unit of specific heat capacity is Jkg-1 K-1.
