Heat capacity or thermal capacity is defined as the amount of heat energy required to raise the temperature of a body by \(1°C\). It is denoted by \(C'\).

It is mathematically represented by,

$\begin{array}{l}\mathit{Heat}\phantom{\rule{0.147em}{0ex}}\mathit{capacity}=\frac{\mathit{Quantity}\phantom{\rule{0.147em}{0ex}}\mathit{of}\phantom{\rule{0.147em}{0ex}}\mathit{heat}\phantom{\rule{0.147em}{0ex}}\mathit{required}}{\mathit{Raise}\phantom{\rule{0.147em}{0ex}}\mathit{in}\phantom{\rule{0.147em}{0ex}}\mathit{temperature}}\\ {C}^{"}=\frac{Q}{T}\end{array}$

The SI unit of heat capacity is \(J/K\). It is also expressed in \(cal/°C\), \(kcal/°C\) or \(J/°C\).
