the chemical reaction by which a substance (such as cement) combines with water, giving off heat to form a crystalline structure in its setting and hardening
the incorporation of water molecules into a complex with those of another compound
This is the level of fluid in the body The loss of fluid, or dehydration, occurs when you lose more water or fluid than you take in Your body cannot keep adequate blood pressure, get enough oxygen and nutrients to the cells, or get rid of wastes if it has too little fluid
The chemical reaction that occurs when water is added to cement, causing it to harden back to top
the chemical reaction by which a substance (such as Portland cement) combines with water, giving off heat to form a crystalline structure in its setting and hardening
any compound that contains water of crystallization cause to be hydrated; add water or moisture to; "hydrate your skin" become hydrated and combine with water supply water or liquid to in order to maintain a healthy balance; "the bicyclists must be hydrated frequently
A compound formed by the union of molecules of water with other molecules or atoms Under certain conditions, natural gas may unite chemically with free water to form hydrates, a solid compound resembling packed snow, at temperatures above the freezing point of water
A substance which does not contain water as such, but has its constituents (hydrogen, oxygen, hydroxyl) so arranged that water may be eliminated; hence, a derivative of, or compound with, hydroxyl; hydroxide; as, ethyl hydrate, or common alcohol; calcium hydrate, or slaked lime
If a substance hydrates your skin, it makes it softer and less dry. After-sun products will cool and hydrate your skin. = moisturize. to supply someone or something with water to keep them healthy and in good condition dehydrate. a chemical substance that contains water
Water chemically combined with a substance in such a way that it can be removed, as by heating, without substantially changing the chemical composition of the substance
