Question

Define the vapourisation point?

Answer 1

Vaporization point:

• Vapourisation can be defined as the process in which the liquid state transforms into the vapor state.
• The fixed temperature at which a liquid state is converted into a gaseous state due to the process of vaporization is known as the vaporization point.

Factors affecting the Rate of Vaporization:

• Rate of vaporization depends upon the concentration of an evaporating substance in the air.
• Intermolecular Forces: The larger the forces in the liquid state that hold the molecules together, the more energy is required by the molecules to get to escape.
• Temperature: The higher the temperature of the material, the larger will be the kinetic energy of the molecule and therefore the rate of evaporation will be faster.
