Solution

Latent heat — The required heat to change the physical states of matter without changing its temperature

  • It is absorbed or released energy during changing the physical states of matter
  • It is two types Latent heat of fusion, Latent heat of vapourization

Latent heat of fusion — It is the amount of energy that must be supplied to a solid substance in order to change its physical state and convert it into a liquid [ when the pressure of the environment is kept constant ]

  • For example — Ice can be converted into liquid at 3.35 X 105 J kg-1

Thus, The value of Latent heat of fusion of ice is 3.35 X 105 J kg-1
