Evaporation occurs as a result of the energy transfer between molecules due to random collisions that can excite molecules to turn from liquid to gas. While some level of evaporation can occur at a temperature below the liquid's boiling point, adding energy, typically t...


Water evaporates when molecules at the interface of water and air have enough energy to escape the forces that hold them together in the liquid. Evaporation, along with boiling, is a type of vaporization.


Evaporation describes the process of a liquid changing to a gas. Usually, the surface parts of a pool of liquid vaporize into a vapor or gas first. Evaporation occurs in both cold and warm liquids.


Water begins to evaporate whenever its molecules speed up enough to break free from their bonds. A water molecule, or H20, is made of two hydrogen atoms and one oxygen atom.


Although the rate at which water evaporates varies depending on temperature, humidity, wind speed and other factors, the average swimming pool loses about 1/4 inch of water per day. Direct sunlight also speeds the rate of outdoor water evaporation.


During evaporation, water rises into the atmosphere and condenses into clouds. When the clouds absorb too much moisture and become heavy, the moisture falls to the ground in the form of precipitation. This is known as the water cycle, which involves evaporation, condens...


Canned evaporated milk can last for one more year past its printed expiration date when stored in the pantry. Once opened, a can of evaporated milk should be stored inside the refrigerator and must be consumed within 3 to 4 days.
