The specific heat capacity of a material or liquid is the term used to describe the amount of energy used to raise the temperature of 1 kg of the material/liquid by 1 K.

The technical term for specific heat capacity, also referred to as specific heat, is cp and is measured in kJ/kg K.

Specific heat capacity is dependent on the temperature of the medium. The specific heat capacity of water in a heating system at a temperature of between 20–90 oC is round 4.2 kJ/kg K.
