Question

How heat capacity of body is related to its specific heat capacity?

Answer 1

1. Heat capacity is the heat required to raise the temperature of the body by $1°$. Denoted by $Q$
2. While Specific Heat capacity is the energy required to raise the temperature of a $1kg$ substance by one degree. Denoted by $c$.
3. Specific heat and Heat capacity is related by the following relation $Q=mc\Delta T$ where $T$ is temperature, $m$ is mass of the substance, $Q$ is heat capacity and $c$ is the specific heat capacity.
4. If we substitute $m=1$ and $∆T=1$ then $Q=c$
5. Therefore, $c$is the heat change involved in the change of unit temperature in unit mass substance.
