The document discusses different processes that water undergoes: boiling, melting, freezing, evaporation, and condensation. It explains that boiling turns water into gas, melting turns ice into liquid, and freezing turns liquid water into ice. Evaporation turns water into vapor at any temperature, and condensation is part of the water cycle where water changes states between vapor, liquid, and solid as it moves from the earth's surface to the sky and back through evaporation and condensation.

1. WATER MATTERS

2. 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

3. 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

4. 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.

5. EVAPORATION
• 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.

6. 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
