Question

Specific heat is defined as heat required to raise temperature of unit mass by?

RankGuru · Accepted Answer

1. **Definition**: Specific heat capacity ($c$) is the quantity of heat required to raise the temperature of a unit mass (usually $1$ kg or $1$ g) of a substance by $1$ unit of temperature.
2. **Units**: Common units are J/(kg·K) or J/(kg·$^\u00circ$C).
3. **Temperature Unit**: Since a change of $1$ K is identical to a change of **$1^\circ$C**, '1 degree' is the defining unit.
4. **Equation**: $Q = m c \Delta T$. If $m=1$ and $\Delta T=1$, then $Q=c$.
