Hey harini
Gypsum is a naturally occurring mineral. Plaster of Paris and gypsum both contains calcium sulfate’s hydrate form, but their water content in a molecule differs from each other.Plaster of Paris is made from Gypsum .  When added water to plaster of Paris, it will re-form into gypsum.
USES OF PLASTER OF PARIS
It is commonly used to precast and hold parts of ornamental plasterwork placed on ceilings and cornices. It is also used in medicine to make plaster casts to immobilize broken bones while they heal, though some orthopedic casts are made of fibreglass or thermoplastics.
