well it probably forms plaster.
A2. Plaster of Paris as usually bought has been dried - the water of crystallization has been removed.
When you re-hydrate the material, the molecules are able to take up this water, and form new inter-locking crystals. This we recognize as a solid.
When it is applied as a plaster cast to immobilize a broken joint, usually more water is used (to aid working) than is need for the setting process. This water evaporates slowly, but cools the limb due to evaporative cooling.

What happens when plaster of Paris mix with water?
Plaster of Paris is formed from gypsum. The gypsum is heated to 150 decrees Celsius and becomes a dry powder. When this powder is mixed with water it re-forms into a paste and eventually hardens into a solid. The powder mixed with water is held together by hydrogen bonds in the water molecules. This is a week bond that is easily broken. When Plaster of Paris and water are mixed together they undergo a chemical change. The particles rearrange to make a completely new substance. When plaster of Paris and water are mixed together the mixture becomes warm releasing energy in the form of heat therefore undergoing a chemical change.
Can you separte plaster of Paris and water?
