BSL Physics Glossary - specific heat capacity - definition

First have a look at the formula: 

Eh=C x m x DT

Eh means energy, equals C (that means the heat capacity of any material) times the mass of that material, times the temperature change, which could be up or down.

So the specific heat capacity of any material means the energy needed to change 1 kg of the material to heat it by 1 degree Celcius, or to cool it down by 1 degree Celcius. The energy might heat the material or it might be lost from the material. 

So for example if C = 100. That means 100 joules of energy are needed to change 1 kg of that material to heat it by 1 degree Celcius or to lose 1 degree Celcius.
