During condensation, water vapor changes from a gas state to a liquid state as it loses heat energy. This process occurs when the temperature of the water vapor drops below its dew point, causing the water molecules to come together and form liquid droplets. Condensation commonly happens when warm, humid air comes into contact with a cooler surface.
Water at 0 Psi.g. and at sea level boils at 212 degrees.
If you begin with 1 lb of water at 32 degrees in a tea kettle on a stove top and bring it to boiling you will have added 180 BTU's. (British Thermal Units) - One BTU will raise a lb of water 1 degree F. The temperature of the water will be 212 degrees.
Now continue to boil the water until the entire lb of water evaporates.
At this point you will have added 970 more BTU's. These Btu are known as Latent Heat.
Latent is Latin for "hidden". You cannot measure this heat with a thermometer.
Imagine doing this in a closed kettle that was tight and would allow no steam to escape.
The one lb of water will boil at 212 degrees. 970 more BTU's will be added.
Turn off the heat supply and watch the kettle. You won't see them but those 970 BTU's will transfer from inside the kettle to the cooler air outside the kettle. Carefull place your hand apporx. 1 inch from the surface of the kettle and you will feel the heat.
As this transfer of heat takes place the steam simply changes state back from a gas to a liquid.
Just the opposite of watching ice melt.
Look up Steam Tables and you can learn more.

Yes, distillation involves two changes of state: first, the liquid is vaporized through heating, and then the vapor is condensed back into liquid form through cooling. This process allows for the separation of components based on their different boiling points.
The condensation point for a gas is the temperature at which the gas changes into its liquid state through the process of condensation. It is the reverse of the boiling point, where a liquid changes into its gas state.
Condensation is the process by which a gas or vapor changes into a liquid state due to a decrease in temperature or an increase in pressure. It is the opposite of evaporation, where a liquid changes into a gaseous state.

Condensation is the process of a vapor becoming a liquid. The term condensation can also be used as a noun to describe the liquid that is the outcome of the process of a vapor becoming a liquid.

It is called condensation.
Condensation occurs when a gas changes state to a liquid.
