Question

What is Latent Heat?

• A. It is the heat given to a body and simultaneously the body releases it to the atmosphere
• B. It is the heat given to a body to heat it by 1${}^o$C
• C. It is the heat given to body to change its state at constant temperature
• D. None of the above

Answer 1

The correct option is (C) It is the heat given to the body to change its state at a constant temperature

1. Latent Heat for a body is defined as the heat given to the body to change its state at a constant temperature.
2. We know that at 100 degrees Celsius water boils and changes into vapor so at that time heat given is called the latent heat of vaporization.

Hence, option C is correct.
