Dehydration

Dehydration is the removal of water (hydor in ancient Greek) from an object. Medically, dehydration is a serious and potentially life-threatening condition in which the body contains an insufficient volume of water for normal functioning.

In non-medical usage, there are many methods of dehydration, with the most common being the application of dry heated air. This causes evaporation of the surface water, which is replaced by water internally. Less common methods include freeze drying and supercritical drying. Drying is often used as a method of food preservation and is also used to obtain absolute alcohol.
