What does evaporation mean?

Evaporation is the process of changing from a liquid or solid state into vapor (like fog, mist, or steam).

Evaporation is a noun form of the verb evaporate. Both terms are typically used in the context of water turning into water vapor.

Water evaporates when it changes into steam through boiling, but in scientific terms, evaporation typically refers to the change of a liquid into a vapor at a temperature below the boiling point, such as the evaporation of water from the surface of the ocean. In this way, evaporation is an important part of the water cycle.

The verb evaporate can also be used in a figurative way meaning to disappear, and evaporation can be used in this figurative way as well.

Example: The evaporation of the dew from the grass each morning happens more quickly in the sunny parts of the yard.

Where does evaporation come from?

The first records of the word evaporation come from the 1300s. It ultimately derives from the Latin verb ēvapōrāre, meaning “to disperse in vapor.” The word vapor is at the heart of evaporation and comes from the Latin word meaning “steam.”

When you leave out a glass of water and it eventually dries up, it doesn’t just disappear—it evaporates (which, yes, is a bit like disappearing into thin air). Scientifically speaking, evaporation takes place at the surface of a liquid, where the molecules with the highest kinetic energy (the ones with the highest temperature) are able to escape—often by floating off into the atmosphere. This means that evaporation is often a result of added heat, such as from a burner on the stove or the sun.

Evaporation is one step in the water cycle, in which water, such as on the surface of oceans, lakes, and other bodies of water, turns into water vapor. The cycle continues as the vapor condenses to form clouds and is then released through precipitation, such as rain and snow.

Evaporation is usually discussed in the context of liquids, but it can happen to solids, too. If you leave ice cubes in your freezer, they’ll eventually evaporate.

Scientific definitions for evaporation

evaporation
[ ĭ-văp′ə-rāshən ]

The change of a liquid into a vapor at a temperature below the boiling point. Evaporation takes place at the surface of a liquid, where molecules with the highest kinetic energy are able to escape. When this happens, the average kinetic energy of the liquid is lowered, and its temperature decreases.

evaporation

The changing of a liquid into a gas, often under the influence of heat (as in the boiling of water). (See vaporization.)
