| Specific Latent Heat | Specific Heat Capacity |
|---|---|
| Specific latent heat involves the amount of energy needed to change the state of 1kg of material, without changing the temperature. | The specific heat capacity of a substance is the amount of energy required to raise the temperature of one kilogram of the substance by one degree Celsius. |
| Energy,E = mass,m x Specific latent heat, L | Energy,E = mass,m x specific heat capacity,c x temperature change,Δθ |
| The value for specific latent heat will depend on the physical state of the substance. In most cases specific latent heat of vaporisation is higher than specific latent heat of fusion. | The value for specific heat capacity is specific to each substance and is the same regardless of the temperature. |
| Units: J/kg | Units: J/kg ⁰C |
