What among the following is not correct about latent heat?a) Latent He...
Ans: b
Explanation: Latent Heat is defined as the amount of heat absorbed or given out by a body during the change of state. It is of two types:
(1) Latent Heat of Fusion: The latent heat of fusion of a substance is quantity of heat required to change unit mass of solid substance from solid state to liquid state.
The latent heat of fusion of ice is 80 cals.
(2) Latent Heat of Vaporization:
• It is the quantity of heat required to change unit mass of liquid substance from liquid to vapour state while temperature remaining constant.
• The latent heat of vaporization of water is 536 cals.
• Latent heat of vaporization is maximum at 0°C and decreases on increasing temperature.
• Latent heat of vaporization of water decreases on increasing pressure or we may say that the latent heat of vaporization decreases with increase in boiling point.

What among the following is not correct about latent heat?a) Latent He...
Explanation:
The correct answer is option 'B': Latent heat of vaporization of water increases with an increase in boiling point.
Definition of Latent Heat:
Latent heat is the amount of heat energy that is either absorbed or released by a substance during a phase change (such as melting or boiling) without a change in temperature.
Explanation of options:
a) Latent Heat is defined as the amount of heat absorbed or given out by a body during the change of state.
This statement is correct. Latent heat refers to the heat energy absorbed or released by a substance during a phase change, such as solid to liquid (fusion) or liquid to gas (vaporization).
b) Latent heat of vaporization of water increases with an increase in boiling point.
This statement is incorrect. The latent heat of vaporization is the amount of heat energy required to convert a liquid into a gas at its boiling point. It is a characteristic property of a substance and does not depend on the boiling point. For water, the latent heat of vaporization is approximately 536 calories per gram.
c) The latent heat of fusion of ice is 80 cals.
This statement is incorrect. The latent heat of fusion is the amount of heat energy required to convert a solid into a liquid at its melting point. For ice, the latent heat of fusion is approximately 80 calories per gram.
d) The latent heat of vaporization of water is 536 cals.
This statement is correct. The latent heat of vaporization for water is approximately 536 calories per gram. This means that it takes 536 calories of heat energy to convert 1 gram of water at its boiling point into steam.
In conclusion, option 'B' is the incorrect statement. The latent heat of vaporization of water does not increase with an increase in boiling point.
The correct answer is option 'B': Latent heat of vaporization of water increases with an increase in boiling point.
