Charcoal does not produce flame because

Options

A. It is a non-combustible substance
B. It undergoes explosion immediately when it comes in contact with fire.
C. It is a liquid fuel
D. It does not produce vapours.

Explanation

### Step-by-Step Solution:

1. **Understanding Combustion**:
- Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light. This reaction can produce a flame if the substance is flammable.

2. **Properties of Charcoal**:
- Charcoal is primarily composed of carbon. It is produced by the pyrolysis of wood, which means it is created by heating wood in the absence of oxygen.

3. **Flammable vs. Inflammable Substances**:
- Flammable substances ignite easily and produce flames when burned. Inflammable substances do not ignite easily and do not produce flames under normal conditions.

4. **Why Charcoal Does Not Produce Flame**:
- Charcoal does not produce a flame when it burns because it burns at a lower temperature and does not release volatile gases that can ignite. Instead, it glows and produces heat without a visible flame.

5. **Conclusion**:
- Therefore, the reason charcoal does not produce a flame is due to its composition and the nature of its combustion process, which does not involve the release of flammable gases.
