Question

Latent heat of fusion is the amount of heat energy required to
change
1 kg of solid into liquid at its melting point
1 kg of liquid into gas at atmospheric pressure at its
boiling point

1 kg of solid into liquid at its boiling point
O 1 kg of gas into solid at its boiling point​

Answer 1

Answer:

Explanation:

Latent Heat of Vaporisation: The amount of heat energy that is required to change 1 kg of liquid into vapour at atmospheric pressure at its boiling point is known as the Latent Heat of Vaporisation. Sublimation: Matters change their state from solid to liquid and from liquid to gas on the application of heat. The amount of heat energy required to change the state of 1 kg of a substance at its melting point is called the specific latent heat of the substance. The specific latent heat of water is: l f = 3 ⋅ 34 × 10 5 J k g − 1 for fusion (solid→liquid) or freezing (liquid→solid)
