Question

Latent heat of fusion (or vaporisation) is the heat energy that is absorbed by a solid (or liquid) without showing any rise in temperature.

• A. True
• B. False

Answer 1

The correct option is A

True

The temperature of any substance remains constant during the change of state because the heat energy supplied is used up in changing the state of matter by breaking several bonds or attractive forces. Since this heat energy is used up in breaking bonds and not for increasing the kinetic energy of the particles, the temperature remains contant during the process.
