NEET Chemistry: Solid State questions with solutions

Q1. When molten sulphur is suddenly cooled by pouring into water, it takes the form of :

1. Milk of sulphur.
2. Colloidal sulphur
3. Flower of sulphur.
4. Plastic sulphur.

Answer: Plastic sulphur.

When molten sulfur is poured into cold water, it cools so quickly that the atoms cannot arrange into the usual crystalline form. This produces plastic sulfur, an amorphous, elastic modification of sulfur.
