Viscosity of sulphur increases when molten sulphur is heated from `120^(@)C" to "160^(@)C`. Why

Explanation

To understand why the viscosity of molten sulfur increases when heated from 120°C to 160°C, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Viscosity**:
Viscosity is a measure of a fluid's resistance to flow. A higher viscosity means that the fluid flows less easily.

**Hint**: Remember that viscosity is related to the internal friction within the fluid.
