Why synthetic fibres burn different from natural fibres?

Explanation

**Step-by-Step Solution:**

1. **Understanding Synthetic and Natural Fibres:**
- Synthetic fibres are man-made materials created through chemical processes, while natural fibres are derived from plants or animals.

2. **Burning Characteristics of Synthetic Fibres:**
- When synthetic fibres burn, they tend to melt due to their chemical composition. This melting occurs because synthetic fibres are made from polymers that have a lower melting point.
- Additionally, burning synthetic fibres releases a distinct chemical smell, which is a result of the combustion of the synthetic materials.
