What's the difference between evaporation and distillation with an example.?

Answers

Answer:

The main difference between evaporation and distillation is that evaporation is a process that involves a change in the state of matter while distillation is a process of separation. While the vaporization in evaporation occurs below the boiling point, the vaporization in distillation occurs at the boiling point.

Explanation:

Evaporation might occur when the sun heats up a puddle, and the water gets evaporated into the air. Distillation is a process used to purify water, and requires water to be boiled by a stove or fire.
