dehydration
Quick Summary
Dehydration is the loss of water from a substance, most commonly referring to the depletion of body fluids in physiology. In chemistry, dehydration is a reaction where elements of water are removed from a molecule, often to form an alkene. This process typically involves warming an alcohol with a strong dehydrating acid, like sulfuric acid.12
Evaporation is a related process where a liquid transitions to a gas below its boiling point, such as water entering the atmosphere as vapor in the water cycle. This is crucial for energy exchange in the Earth-atmosphere system and influences weather and climate. Factors affecting evaporation include temperature, humidity, wind speed, and solar radiation. Dehydration can also refer to preserving food by removing water, as seen with raisins (dehydrated grapes).34
