Question

Explain with examples of water 1 latent heat fusion. 2 latent heat of vaporization

Answer 1

1) latent heat of fusion - It is the amount of heat energy req. to convert 1 kg of solid to liquid at izs melting point. For eg - ice melts at 0'c into water.
2) latent heat of vaporisation - It is the amount of heat energy req. to convert 1 kg of liquid to gasous form at its boiling point. For eg - water evaporates into vapour at 100' c.

Answer 2

Answer:

• latent heat of fusion :- It is the amount of heat energy required to change 1 kg of solid into liquid at its melting point. eg- ice changes into water at 0° temperature.

• latent heat of vaporization:- the amount of heat energy required to change 1kg of liquid to gas at atmospheric pressure at its boiling point. eg- water changes into vapours at 100° temperature
