Question

Give the reason for the increase in rate of evaporation of a liquid when temperature of the liquid is increased.

Answer 1

Hint:Evaporation is a form of evaporation that occurs on a liquid's surface as it transitions from a liquid to a gas. The evaporating liquid must not be saturated in the surrounding steam. As the molecules of a solvent collide, they transfer energy to one another depending on how they collide.

Complete answer:
Evaporation is the mechanism by which a liquid (usually water) is converted into a gas or vapour without being heated to boiling point. The following are the main factors that influence the rate of evaporation of a liquid:
-Temperature
-Surface area exposed
-Liquid partial pressure in the air above it.

If the temperature rises, the molecules' kinetic energy rises, allowing them to resist the force of attraction between molecules and evaporate more quickly. As the temperature of a liquid (in this case, water) is raised, the kinetic energy of the individual molecules that make up the liquid rises as well.

This increase in energy allows the liquid molecules to transcend the intermolecular forces of attraction (which keep the liquid together) and escape into the atmosphere as a gas. The temperature of the ambient atmosphere can also lead to faster evaporation so hot temperatures can transfer their heat to the liquid.

Note:Water quickly evaporates at the boiling point (212° F, 100° C), but it evaporates somewhat more slowly at the freezing point due to the need of energy to sever the ties that tie water molecules together. When the rate of evaporation approaches the rate of condensation, net evaporation occurs.
