Question

What is a change? Explain why water cycle is considered as an example of reversible changes.

Answer 1

Answer:

In the water cycle, water changes the three states of matter. i.e on evaporation the surface water (liquid state) changes to water vapour (gaseous state) and forms clouds. ... The water on the surface again evaporated due to sun's heat and the water cycle continues. Thus water cycle is a series of reversible changes.
