What happens with water vapor when its cooled?
when water vapour is cooled it condenses and falls as rain
Why does corks below the water rise to the surface?
Cork consists of a material which is lighter, or less dense than water so it naturally rises to the surface.
Solid condensation on a surface that is below 0C is known as?
Water vapour changing to solid on a surface is sublimation of the vapour. For water the product is referred to as rime or hoarfrost.
Before ice can form on a lake all the water in the lake must be cooled to?
no it can form any time. ^^^^^^^ thats bS
What changes do you think when water heated and cooled?
If the water is heated, the germs and harmful bacterias get killed So, this water gets pured. If the water is cooled, the dead germs get cleaned and then the water is 100% pure.
Can air be warmed or cooled by the surface below?
This is a very easy question to answer . Yes the air can be cooled or warmed by the surface below it because say if there was to be a earthquake right now in the ocean the heating of the surfaceunder the water would cause the water the make enormous wave and for te world to shake and depending on how hot the surface is heating.
Why does all the water in a lake have to be cooled to 4 degrees Celsius before water can be cooled below 4 degrees Celsius?
Water in a lake is usually cooled by the cold air above its surface rather than from the ground underneath it. As the top layer of water cools its density increases and so it sinks to the bottom, bringing other water up to the surface. This water is then cooled. This carries on until the temperature reaches 4 deg C when the density reaches a maximum. Further cooling lowers the temperature of the top layer but now its density is less than that of the water below so the top layer stays on top until it freezes (if it is cold enough). That is how you can get lakes with a frozen surface but liquid water below which can sustain aquatic life and also destroy human or other life forms that fall through the ice!
When air high above the earth's surface is cooled below the dew point it is likely to form?
When air high above the Earth's surface is cooled below the dew point, it is likely to form clouds. Clouds are visible mass of liquid droplets or frozen crystals made of water.

Why the surface layer of water in the poles is colder than the layer just below it yet the colder layer floats on top?
Due to the anamolous behaviour of water, the surface water being cooled by the external environment falls below 4C and begin to expand. when this surface water molecules expand they rise to the top due to a decrease in density as compared to the water below the surface. the cooler the temperature henceforth, the more the expansion of the surface water molecules till it solidifies to become ice. this surface ice then acts as an insulator and prevents the exchange of heat between the environment the water molecules just below it, thus maintaining the temperature of the water below the surface as constant.
Can water molecules evaporate at the surface or below the surface?
water molecules can evaporate at the surface but not below the surface
Does heat move in or out of water cooled below 0 degrees?
Out
What happened to water vapor before it turns to water?
It cooled.
Ground water exists below the surface of the earth?
The answer is false. Ground water is water retained below earth's surface. BELOW THE SURFACE.
What can cause water vapor in the air to be cooled?
The process is called condensation. It occurs when the water is cooled below its boiling point due to the temperature in the environment cooling it.
When moist air is cooled below its dew point water will?
The water will condense forming dew.
What is the water below the surface?
Ground water.
