Answer 1

• The latent heat of fusion is defined as the amount of heat absorbed by a specific quantity of a solid substance to get converted into its liquid state without changing the temperature.
• It is also known as enthalpy of fusion.
• J/kg (or JKg^-1) is the SI unit of latent heat of fusion.
• Latent heat of fusion of water is the amount of heat energy that must be supplied to convert 1 kg of ice into water without changing the temperature of the surroundings that is at zero degrees celsius.
• The latent heat of fusion of water is 333.55 kilojoules.
