properties of plaster of paris?​

Answer 1

$\huge\mathbf{\underline{Answer}}$

1. Paris is a white powder.
2. Plaster of paris has a very remarkable property of setting into a hard mass on wetting with water.

Answer 2

Answer:

PLASTER OF PARIS is non-flammable and non-combustible. Has generally low chemical reactivity but can act as an oxidizing agent under extreme conditions. Decomposes at high temperature to generate toxic oxides of sulfur. Reacts exothermically but slowly with moisture in the air or water to form gypsum CaSO4.

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 many modern orthopedic casts are made of fibreglass or thermoplastics.
