WATER MATTERS

BOILING • BOILING IS THE PROCESS BY

WHICH A SOILD CHANGES INTO LIQUID. • BOILING IS THE PROCESS WHERE

BY LIQUID CHANES TO GAS STATE•WATER BOILS AT 100 DEGRES

MELTING• MELTING IS THE PROCESS BY WHICH A SOLID

CHANCHES TO LIQIUD• ICE BEGINS TO MELT AT O DEGRES .• THI TEMPRETURE IS KNOW AS THE MELTING POINT

OF ICE

freezing• Freezing is the process by which a liquid changes

into a solid• Water freezes to become ice at 0 degrees celcius .• This temperature is know as the freezing point of

water.

• Water can change into water vapour through the process of evaporation

• This process takes place at all time and at any temperature

• The rate of evaporation is affected by the temperature of the surrounding ,wind and the exposed surface area.

EVAPORATION

CONDENSATION and WATER CYCLE• In the water cycle ,water changes from one state to

another through the processes of evaporation and condensation

Water is constantly moving from the surface of the earth to the sky and back again.

This is known as the water cycle
