Specific latent heat

• Specific latent heat - the amount of energy required to change 1kg of a substance from one state to another.
• Specific latent heat of vaporisation - energy change when a substance changes between liquid and gas.
• Specific latent heat of fusion - energy change when a substance changes between solid and liquid
• E = m*l

  E = energy required or released

  M = mass

  L = specific latent heat
