specific latent heat and specific heat capacity

• specific heat capacity is the energy required to raise the temperature of 1kg of a substance by 1 degree celcius
• energy = mass x specific heat capacity x temp change
• specific latent heat is the energy to change the state of 1kg of a substance without a change in temp
• the substance needs to be at the right temp to change first
• • specific latent heat of fusion is energy to melt/freeze
  • specific latent heat of vaporisation is energy to boil/condense
• energy is absorbed when melting and evaporating

  energy is released when freezing and condensing
• energy = mass x specific latent heat
