Question

The amount of heat required to change from liquid state to gaseous state without rise in its temperature is called latent heat of vaporisation.

• A. True
• B. False

Answer 1

The correct option is A True

The statement is true, the amount of heat required to change from liquid state to gaseous state without rise in its temperature is called latent heat of vaporisation.

Latent heat of vaporization is the physical property of substance. When a material in liquid state is given energy, it changes its phase from liquid to vapor, the energy absorbed is known as latent heat of vaporization. For water, its value is $2260KJ/Kg$ or $40.8Kg/mol$.
