Question

Why does latent heat not change the temperature of the thermometer when water is boiling at ${100}^{0}C$?

• A. All the energy is used to change the state of water
• B. Water particles start losing energy above ${100}^{\circ }C$
• C. The particles of water start slowing down at ${100}^{\circ }C$
• D. Latent heat does change the temperature of the thermometer

Answer 1

The correct option is A

All the energy is used to change the state of water

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. So the temperature remains the same only the state of water is changed.
