Water Cycle and Changes of State

Steam

Is produced when water boils

Changing States of Water

Condensation

Takes place anytime

Lose heat and changing from gaseous state to liquid state

Boling

Gain heat and changing form liquid state to gaseous state.Takes place at 100 degrees Celcius

Evaporation

Factors

Wind

The stronger it is, the higher the rate of evaporation

Humidity

The higher it is,the lower the rate of evaporation.

Area of exposed surface

The larger it is ,the higher the rate of evaporation

Temperature

The higher it is,the rate of evaporation

Gaining heat and changing from liquid state to gaseous state and takes place at any temperature.

Melting

Gain heat and change from solid to liquid state and takes place at 0 degrees Celcius or higher.

Freezing

Lose heat and change from liquid to solid state.It takes place at 0 degrees Celcius

Water is heated up by the sun and rise to form water vapour.This process is called evaporation.Then,the water vapour condenses to form water droplets,.This process is called condensation.After that,they join together to form clouds.They then get heavy and fall as hail,rain,sleet or snow-depending on the temperature.This process is called precipitation.They then go back into the water bodies or soak into the ground .This process is called collection.Then ,the water cycle starts again.

Water

Is the only thing which exists in all three states

Liquid State

Water Droplets

Solid State

Ice,Snow

Visible

Gaseous State

Water Vapour,Steam

Invisible

Covers 2/3 of the Earth`s surface

Comes from Water Bodies

Impurities will lower the freezing point and higher the boiling point.
