## Heat Capacity

The heat capacity, or the specific heat of a material, is the proportionality constant between the increase in temperature and the increase in heat absorbed by the material per unit mass, per unit temperature.

H = m C (T2 - T1)

where:
H = Heat absorbed by object
m = mass of object
C = heat capacity of material in the object
T1 = starting temperature
T2 = final temperature

The unit used for C should match those used for H, m and T.

For example: If a material has a heat capacity of 5 J g−1 K−1 then increasing the temperature of 1 gram of that material by 1 °C will cause it to absorb 5 J.
