Classify the following solids in different categories based on the nature of intermolecular forces operating in them :
Potassium sulphate, tin, benzene, urea, ammonia, water, zinc sulphide, graphite, rubidium, argon, silicon carbide.

Explanation

To classify the given solids based on the nature of intermolecular forces operating in them, we will categorize them into four main types: ionic solids, metallic solids, molecular solids, and covalent (network) solids. Let's analyze each solid one by one.

### Step-by-Step Solution:

1. **Potassium Sulphate (K₂SO₄)**:
- **Classification**: Ionic Solid
- **Intermolecular Forces**: Ionic bonds (electrostatic forces between cations and anions).
