What causes the liquid water to turn into water vapor?

Answer 1

Water vapor is water in its molecular form, separate units of H2O floating around in the air.

But air can only carry a certain amount of water vapor. When it gets to be too much water vapor, the water molecules will bind together to form tiny droplets until the remaining free H2O molecules can again be carried by the air.

The process in which excess H2O molecules bond together to form a liquid is called condensation.

The amount of water vapor one amount of air can carry is dependent on temperature, the warmer it is, the more H2O molecules you can have for each unit of air. And also the reverse - the colder it gets, the fewer H2O molecules can be carried in the air.

So the most common cause of condensation is moist air being cooled down.

When you see drops of water forming on something that's just been taken out of the fridge, this is what's happening.

Answer 2

Water vapors makes up only a few percent of the mass of the atmosphere. However, this small amount of water vapor has in oceans and water bodies changes to a gas, water vapor. The mount of water vapor in the air is called humidity

Answer 3

The addition of heat energy to the point of vaporization.

Answer 4

This process is called condensation or liquefaction.
