Question

Describe latent heat of vaporization.Why does temperature remain constant during boiling of liquid? Please answer fast

Answer 1

Latent heat of vaporization the amount of heat required to convert 1 kilogram solid into its liquid form is known as latent heat of vaporization

For example

For water latent heat of vaporization is 226 kilo joule per kilogram

During the change of state the heat energy is used by the particles To overcome the inter particular force among the particles hence this energy is hidden.

Answer 2

The amount of heat required to change 1 kg of liquid into solid on atmospheric pressure at its boiling point is known as latent heat if vaporisation.
The temperature does not rise because it is used up to overcome the forces of attraction between the particles and hence there is no increase in kinetic energy.
