Solution

The correct option is B vapourisation
The amount of heat required to convert unit mass of a liquid into its vapour state without change in its temperature is called latent heat of vaporization.
The term 'latent' means hidden, which is used because the temperature does not rise even on supplying heat during the process.

Q. The energy supplied to convert a unit mass of a liquid into gas at its boiling point is known as the latent heat of .

It has been observed that temperature remains constant till all solid melts into liquid. The heat supplied is used for changing a solid state into its liquid state by overcoming the particle-particle attraction force. The solid substance absorbs heat energy without showing any rise in temperature. This heat energy is called latent heat. The amount of heat required to convert a unit mass of a solid into its liquid state, without a change in temperature (i.e. at its melting point) is called the latent heat of fusion.EXPLAIN
