State two differences between Heat Capacity and Specific Heat Capacity

Heat (10)

1. State two differences between “Heat Capacity” and “Specific Heat Capacity”.
2. Give a mathematical relation between Heat Capacity and Specific Heat Capacity.

Answer

i. Heat capacity

1. Heat absorbed by the mass of a body to raise its temperature by 1° C.
2. S.I. Unit is J K^-1
3. Depends on mass and (specific Heat capacity/material)

Specific heat capacity

1. Heat absorbed by unit mass of a body to raise its temperature by 1° C.
2. S.I. unit is J kg-1 K^-1
3. Does not depend on mass (but depends on material)

ii. Heat capacity (C') = mass of the body (m) x specific heat capacity (c)
