When we heat a substance, we transfer energy to it which will increase its temperature. The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kilogram of the substance by 1 degree Celcius.

Different substances have different specific heat capacities. The greater the specific heat capacity, the more energy required for each degree temperature to change. For example the specific heat capacity of aluminium is 900 J/kg degrees Celcius and of copper is 490 J/kg degrees celcius. If we wanted to raise the temperature of 1 kg of aluminum we would need to transfer twice as much energy needed to raise the temperature of 1kg of Copper by the same amount.

The greater mass of substance being heated the more energy required for each degree temperature change.

The equation for specific heat capacity: E= m x c x 0 (feta)

E is energy transfered in J, m is mass in kg, c is specific heat capacity J/kg degrees celcius, 0 (feta) is temperature change
