dew pointWater vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid.
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. Photo from: Wikimedia Commons. Evaporation and condensation are two processes through which matter changes from one state to another.

Condensation. Gases turn into liquids if they are cooled down. This is called condensation.
Explain that cooling invisible water vapor slows the molecules and brings them back in a more condensed form as liquid water (condensation). Heating liquid water speeds up the molecules, spreading them further apart and making them invisible again (evaporation).
When molecules of water vapor return to liquid or solid form, they create cloud droplets that can fall back to Earth as rain or snow—a process called condensation. Most precipitation lands in the oceans.
When the water vapor cools enough, the attractions between the molecules bring them together. This causes the water vapor to change state and become tiny drops of liquid water. The process of changing from a gas to a liquid is called condensation.
When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation. Water vapor (steam) mixes with the air and seems to disappear. A simple example is water boiling in a teapot and escaping into the air.
Solution : During the process of evaporation in a closed container, as the concentration of molecules in the vapor phase increases , some molecules return to the liquid phase , a process called condensation.
Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation.
energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.
