### 5.2:Heat Capacity - Chemistry LibreTexts

Nov 30, 2020 · Rearranging the above Equation gives the definition of the heat capacitance of an object \[ C=\frac{q(J)}{\Delta T(K)}\] This is an important equation because it relates the heat lost or gained by an object to its temperature change. A substance with a small heat capacitance cannot hold a lot of heat energy and so warms up quickly.
