Water and its three states
What is water?
Water is the most common liquid found on Earth. It can be found in oceans, seas, rivers, wells and also in the air
What are the three states of water?
Liquid state
water in water bodies such as ocean and seas
Gaseous state
water vapour and steam
Solid state
ice, iceberg and snow
Ice
melts at 0 degree
water
evaporates
water vapour
condenses
loses heat
boils at 100 degree
steam
gains heat
Freezes at 0 degree
boiling
Boiling is the change in state of water from a liquid (water) to a gas (steam)
evaporation
Evaporation is the change in the state of water from a liquid (water) to a gas (water vapour) due to heat gain
Condensation
Condensation is the change of water from a gas to a liquid due to heat loss
Freezing
The freezing point of water is the temperature at which the liquid (water) changes state to a solid state due to heat loss
