Changes in States of Matter for Water

Matter changes from one state to another when it is heated or cooled

Melting

Melting is a process in which a solid becomes liquid when heated

Boiling

Boiling is a process in which a liquid changes into gas when heated

Evaporation

Evaporation is a process in which liquid changes into gas when it gains heat

Factors that affects the evaporations of water

Hot weather, wind and exposed surface area

Condensation

Condensation is a process in which gas condenses to become liquid when cooled

Freezing

Freezing is a process in which liquid changes into solid when cooled

Boiling and freezing

Water boils changes into steam when heated at 100 ̊C while water turns into ice when it is cooled to 0 ̊C

Cloud and rain (water cycle)

The water cycle is the continuous movement of water from the Earth's surface into the air and back to the Earth's surface again
