Question

Write a note on any two of the following: (Textbook, Pg. 17)
a) Evaporation
b) Condensation​

Answer 1

Answer:

Evaporation: Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.

condensation:Condensation is the process through which the physical state of matter changes from the gaseous phase into the liquid phase. ... When the water in the air comes in contact with a cold surface, it condenses to form water droplets. The opposite of condensation is evaporation reaction.

Evaporation:- The process in which water changes into vapour due to heat, and rises up.
