Define specific latent heat of fusion of ice and also state the numerical value in SI system.
Answers
The value of latent heat of fusion of ice is 3.36×105JKg−1 in S.I. unit of system. The specific latent heat of vaporization of the system is the heat energy needed to change one kilogram of the material in its liquid state at its boiling point to one kilogram of the material in its gaseous state.
The specific latent heat fusion is the heat energy needed to change 1 kg of the ice in its solid state at its melting point to 1 kg of the ice in its liquid state, and that released when 1 kg of the liquid changes to 1 kg of solid
Specific heat of fusion of ice is 0.336 MJ/kg
The specific latent heat of vaporisation of a water is the heat energy needed to change 1 kg of the water in its liquid state at its boiling point to 1 kg of the water in its gaseous state, and that released when 1 kg of vapour changes to 1 kg of liquid
Specific heat of vaporisation of water is 2.26 MJ/kg
