Answer 1

Property of Plaster of Paris:
Plaster of Paris (CaSO₄ · ½H₂O) is a white powder that, when mixed with water, forms a paste that hardens over time. It sets and hardens quickly due to a chemical reaction, making it useful for molding and casting.

Two Applications of Plaster of Paris:
1.
In Medicine:
Plaster of Paris is commonly used to make casts for broken bones. When applied, it hardens and keeps the bone immobilized during healing.
2.
In Art and Architecture:
It is used in creating sculptures, statues, and decorative moldings. It is a popular material for artistic casting and architectural elements due to its easy moldability and fast setting time.

Conclusion:
Plaster of Paris is a versatile material used in both the medical field and in art and architecture due to its quick setting and moldable nature.
