The specific heat capacity is the energy needed to raise the temperature of a given mass by a certain temperature.
The change in temperature of a substance being heated or cooled depends on the mass of the substance and on how much energy is put in. However, it also depends on the properties of that given substance. How this affects temperature variation is expressed by the substance's specific heat capacity (c). This is measured in J/(kg·K) in SI units.

Change in internal energy, ?U (J) = mass, m (kg) x specific heat capacity, c (J/(kg·K)) x temperature change, ?T (K) |
