Question

State two differences between the specific heat capacity and the heat capacity of a substance.

Answer 1

The following are difference between Specific Heat and heat capacity:

1.“Heat capacity” is an extensive variable while “specific heat” is an intensive variable.

2.“Specific heat” has a unit of mass in its equation as recommended by the International Standards of measurement.

3.“Specific heat” is more suitable for use in theoretical and experimental functions.

4.According to SI units, the formula for heat capacity is $C=\frac{Q}{\Delta T}$ while for specific heat it is $C=\frac{J}{kgK}$.
