because it create a layer on the water and cannot evaporate the water and water became safe for use.

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
Mercury can vaporize if heated This means that with enough heat mercury can?
be changed into a gas
Is water vapour in the liquid state?
yes, water vapour is in a liquid state
What is the Difference between airs and gases and water vapour?
Air is the mixture of different gases (like oxigen, nitrogen, co2 e.t.c.) & water vapour. Gases are only gases, here is no water vapour. And water vapour is form after the vapourization of water at high temperature.
How is vapour used in a sentence?
The water vapour condensed on the windows. The vapour rising off the acid made me choke.
What is a Binary Vapour Cycle?
A binary vapour cycle is a representation of a mercury cycle and a steam cycle on a same scale.In this vapour cycle there is comparison between the mercury cycle and steam cycle. In mercury cycle there occurs isothermal expansion of saturated water from boiler into dry saturated steam followed by isentropic expansion followed by condensation of steam and at last heating of steam and thus mercury has completed the cycle in 4 way process. In steam cycle first ther is isothermal expansion which results in converting of saturated water into dry saturated steam followed by superheated process where the steam is superheated followed by isentropic expansion of superheated steam followed by condensation of exhaust steam and at last heating of steam thus completing the cycle.
What does vapor mean in the water cycle?
The clouds seen in the sky is formed from water vapour. It is water that has changed from a liquid into a gas (vapour).
Water vapour forms clouds and returns to earth?
The water cycle.
Is a cloud a vapour?
yes, they are condensed water. See the water cycle!
How does water vapour relate to the water cycle?
After evaporation, water gets converted into water vapor. This is the first step of water cycle.
URGENT why do you use mercury in barometers and not water?
At lower temperatures water will freeze and mercury will not.
What is formed by vapour after evaporation?
More water. Look up the water cycle.
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
What is vapour?
a pure gas of oxygen and hydrogen The water cycle is driven by the Sun's energy. When water evaporates, it turns into the invisible gas called water vapour.
What is water vapour used for?
water vapour is used to put in balloons.[even thouht the balloons can't fly]
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).
Where in the water cycle does water vapor gain energy?
Water gains energy in evaporation to become water vapour.
