Question

Distinguish between the heat capacity of a body and the specific heat capacity of a substance

Answer 1

It is the amount of heat required to raise the temperature of substance by 1 degree Celsius or or 1 kelvin is known as its heat capacity.the SI unit of heat capacity is joule per Kelvin, j/k.

C=Q/∆t.

However specific heat capacity is the amount of heat required to raise the temperature of unit mass of that particular object by 1 degree Celsius or 1 kelvin.specific heat capacity of a material 'c' can be obtained by dividing its heat capacity' C' with its mass 'm'.

C=C/m=Q/m∆t.

SI unit of specific heat capacity is joule per kilogram per kelvin
