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
