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.
The adhesive used in plaster of Paris is water. When water is added to plaster of Paris powder, a chemical reaction occurs that causes the powder to transform into a thick paste that can then be applied to a surface before hardening.
Adding water to plaster of Paris is considered irreversible because a chemical reaction occurs when water is mixed with plaster of Paris, resulting in a new compound called calcium sulfate hemihydrate. Once the reaction is complete and the plaster has set, it cannot be reversed back to its original form.
When plaster of Paris is exposed to air, it undergoes hydration, which means it reacts with water vapor in the air to form a solid material. This process causes the plaster to harden and set into a rigid structure.
No
Plaster of Paris readily hardens when mixed with water.
you get plaster water in other words putty

Plaster of Paris dissolves in water by forming a suspension of particles called a colloid. This happens because the water molecules penetrate the gaps between the plaster particles, causing them to break apart and disperse in the water. This process can be reversed by allowing the water to evaporate, leaving behind the solid plaster material.

Plaster of Paris sets when it comes into contact with water. If a rat eats it, and drinks water it will activate and harden in the rats stomach.

Use a ratio of 2 cups of Plaster of Paris to 1 cup of water. Use immediately once mixed is smooth.
Plaster of Paris (gypsum) is calcium sulfate (CaSO4.0,5H2O) - a compound.
