Question

Why plastic sulphur is elastic in nature?

Answer 1

One of the allotropic forms of sulphur is plastic (or amorphous) sulphur. It is also known as gamma–Sulphur, is a tough elastic substance that is formed when molten sulphur is poured into cold water.

Preparation:

Plastic sulphur is prepared by suddenly cooling the molten sulphur (near its boiling point) by pouring it into cold water. Yellow rubbery ribbons of sulphur are formed. They are very soft and can be stretched easily.
