Question

what is evaporation
explain​

Answer 1

Answer:

Evaporation : It happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.

Answer 2

Answer:-

Evaporation is a form of vaporisation that usually happens on the surface of liquids and it involves the transition of the liquid particles into the gaseous phase. Therefore, this process is said to involve a change in the state of matter of liquids. The surrounding gas must not be saturated with the substance which is evaporating. They transfer energy to each other as the molecules of the liquid collide, depending on how they collide with each other. The liquid particles will generally escape and enter the surrounding air as a gas when a molecule near the surface consumes enough energy to overcome the vapour pressure. The energy extracted from the vaporised liquid as evaporation occurs will decrease the temperature of the liquid, resulting in a process known as evaporative cooling.
