Heat of vaporization.
It takes a lot of energy for something to change state from liquid to gas. That energy is called the heat (or "enthalpy", sometimes, if you want to be pedantic about it) of vaporization.
The energy used to do this comes from taking out some of the thermal energy of the material, which causes it to cool down.

What are other examples of evaporation to cool things down?
Other examples of evaporation to cool things down include sweating in humans, the use of evaporative coolers in buildings, and the cooling effect of a wet towel placed on the skin on a hot day. Evaporation removes heat from a surface as the liquid evaporates into the air, leading to a cooling effect.
Why is evaporation considered a cooling process?
Evaporation is considered a cooling process because when a liquid evaporates, it absorbs heat energy from its surroundings in order to change from a liquid to a gas. This absorption of heat causes the surroundings to cool down, making evaporation a cooling process.
What happens to temperature during evaporation?
During evaporation, the temperature of the liquid decreases because the molecules with higher kinetic energy leave the surface, taking away heat. This causes the remaining liquid to cool down as a result.
What happens to the rate of the evaporation of a liquid as the liquid is cooled?
When a liquid is cooled, the rate of evaporation slows down
What is the relationship between evaporation and the cooling effect it causes in the liquid left behind?
Evaporation is the process in which a liquid turns into a gas. When evaporation occurs, it takes energy from the surrounding liquid, causing it to cool down. This cooling effect happens because the faster-moving molecules escape as gas, leaving behind slower-moving molecules that have lower energy and therefore lower temperature.

If you wanted to slow evaporation from a pot of coffee?
cool it down

Why evaporisation slow in refrigerator?
Evaporation is caused by liquid getting heated up into gas. refrigerators cool the temperature down and increase the time it takes for water to evaporate.
What is the difference between evaporation and boling?
Evaporation is the process where a liquid turns into a gas at temperatures below its boiling point, typically occurring at the surface of the liquid. Boiling is the rapid vaporization of a liquid caused by reaching its boiling point, which happens throughout the liquid volume and not just at the surface.
Why evaporation is low in refrigerator?
It is because the air in the refrigerator's temperature is very low ,thus, the evaporation process is slowed down
What is the name of the process of liquid turning into gas?
It is evaporation
How do you prevent liquid sulfur from evaporating?
You can prevent liquid sulfur from evaporating by storing it in a tightly sealed container to prevent exposure to air. Keeping it in a cool, dark place can also help reduce evaporation. Additionally, minimizing the surface area of the liquid sulfur exposed to air can help prevent evaporation.
Why does a liquid cool when evaporated?
Evaporation Takes Place Layer By Layer. Then Heat, In The Stages Of Evaporation Just Effects The First Layer Of The Liquid . Heat Makes An Increase Of Enegry Between The Particles. The Particles, With That Energy, Trys To Move And Seperate ThemSelves From The Whole Liquid. The Higher Engery Partides Rise, Leaving The Less Engery Ones Behind, There For Making The Liquid Cool.
