Heat is a transfer of energy.

Heat capacity also known as thermal capacity is the amount of heat required to raise the temperature of a mass of substance by 1°C.

Water is known to have a high heat capacity due to its hydrogen bonding among water molecules.

**Formula to calculate heat capacity.**

ΔQ is the change in amount of heat transferred.

ΔT is the change in temperature, ºC.

**Example:**

Determine the heat capacity of copper of mass 70 g if the temperature difference is 20^{o}C if 300 J of heat is lost.

Therefore, the heat capacity is 15 ** **J/^{o}C.
