Solution

The correct option is A
True

This is true. When water starts to boil at $100^{\circ} C$ , the temperature does not rise in the thermometer. All the heat energy is used by the water particles to overcome the interparticle forces of attraction and to change their state from liquid to gaseous. This energy, also known as the hidden energy is called the latent heat of vapourisation.
