Why water vapour is not pulled due to gravity?
A water vapour is a tiny particle of water its weight(mg) is very very small almost negligible so it is not pulled by gravity.
What is the difference between water vapour and steam?
the difference is that water vapour is just one particle that joins together with more and more to form steam
What does boiled water become?
seam or otherwise known as water vapour
Where in the water cycle does water vapor gain energy?
Water gains energy in evaporation to become water vapour.
Which processes of the water cycle show heat being added and which ones show heat beign removed?
How the water cycle and heat are related: Adding or subtracting heat makes the water cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapour. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapour). Ice can change to become water or water vapour. Water can change to become ice or water vapour. Water vapour can change to become ice or water. If heat is taken away from water vapour, it condenses. Condensation turns water vapour into a liquid. If heat is taken away from liquid water, it freezes to become ice. The water cycle involves the sun heating the Earth's surface water and resulting in the surface water evaporating. The water vapour rises into the Earth's atmosphere. The water cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation (which can be rain, freezing rain or snow).

What happens to the particles when water vapour changes into water?
the particle loses the energy and it goes into surrounding environment
What is the difference between water vapour and steam?
the difference is that water vapour is just one particle that joins together with more and more to form steam
What does snow become when evaporated?
Water vapour
What does liquid water become when it evaporates?
steam or water vapour
What does boiled water become?
seam or otherwise known as water vapour
Is water changing to water vapour a reversible or irreversible change?
It is reversible . Water vapour can condense and become liquid. Evaporation and condensation are phases in the water cycle
When does the water vapor become clouds?
When the water vapour has condensed in the air forming cloud
Where in the water cycle does water vapor gain energy?
Water gains energy in evaporation to become water vapour.
The step of the water cycle in which liquid water changes to water vapor is .?
Evaporation causes water to become a vapour.
Which processes of the water cycle show heat being added and which ones show heat beign removed?

When water changes from gas to a solid?
Water as a vapour (gas?) has to condense back to water, which can then become a solid if frozen.
