Question

Give a scientific reason for evaporation of water due to heat of sun is a physical change. ​

Answer 1

Answer:

For the water cycle to work, water has to get from the Earth's surface back up into the skies so it can rain back down and ruin your parade or water your crops or yard. It is the invisible process of evaporation that changes liquid and frozen water into water-vapor gas, which then floats up into the skies to become clouds.

Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.
