Question

Why does the temperature remain constant during boiling?

Answer 1

Boiling point

• At atmospheric pressure, the boiling point of a liquid is the temperature at which it boils and transforms rapidly into a gas.

Reason for not an increase in temperature

• When a liquid, such as water, begins to boil, the temperature of the water does not rise even when the heat supply is constant.
• The excess heat given to boiling water is used to vaporize water, which is known as latent heat of vaporization.
• So, the temperature does not rise because the given energy is used to change the state of the liquid.
