Evaporation from a pot.
An example of evaporation is water turning into steam.
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.
(countable and uncountable, plural evaporations)
From Old French Ã©vaporation, from Latin evaporatio
- There was evaporation of water from the leaf.
- An economical method of evaporation must be found.
- The annual evaporation from water surfaces is from 60 to 150 in.
- The test tube is tightly corked to prevent evaporation, and allowed to stand for some hours.
- The space between the parts of such substances is too large to admit of capillary action; hence the water conveyed to the surface of the soil is prevented from passing upwards any further except by slow evaporation through the mulching layer.
