# Why does heat capacity change with temperature?

Feb 28, 2016

Heat capacity is a physical property that is constant for a specific matter and therefore, it is constant and will not change with temperature.

#### Explanation:

Heat capacity by definition is the amount of heat needed to increase the temperature of one gram (specific heat capacity) or one mole (molar heat capacity) by on degree (${1}^{\circ} C$).

Therefore, heat capacity is a physical property that is constant for a specific matter and therefore, it is constant and will not change with temperature.

However, what changes is the amount of heat, which is represented by:

$q = m \times s \times \Delta T$

where, $q$ is the amount of heat,
$s$ is the specific heat capacity,
$\Delta T$ is the change on temperature.
