Changes In States Of Matter For Water

Changes in states of matter for water

Water can change from one state of matter to another state of matter.
Water matter can change its state through the processes of freezing, melting, boiling, evaporation and condensation.

Clouds & rain

The movement of water from the earth’s surface to the air forms clouds & eventually descends back to the earth’s surface as rain
This process is repetitive & is known as the natural water cycle
The formation of clouds & rain results from the process of changing in state of matter of water
The natural water cycle ensures that the quantity of water is always sustained on the earth’s surface through the formation of clouds & rain
This cycle involves the process of evaporation & the process of condensation

A - Heat from the Sun causes the process of evaporation to take place. Water evaporates from the earth's surface such as land, oceans, rivers & lakes into water vapor.
B - Water vapor that accumulates & cools will condense into fine water droplets & form clouds.
C - As the clouds rise higher in the sky, the cold air causes the water droplets to merge to become larger & heavier which then fall back to earth as rain.
D - Rainwater is absorbed into the earth & will flow back into lakes, rivers & oceans.
