Combustion is an ______ process.

Options

A. Endothermic
B. Exothermic
C. Reactive
D. Neutral

Answer

**Step-by-Step Solution:**

1. **Understanding Combustion**:
- Combustion is a chemical process where a substance reacts with oxygen.
- This reaction typically produces heat and light.

2. **Identifying the Type of Process**:
- In combustion, heat is released as a product of the reaction.
- This release of heat indicates that the process is exothermic.

3. **Evaluating Options**:
- The question asks for the type of process combustion is.
- The options provided include:
- A) Endothermic
- B) Exothermic
- C) Reactive
- D) Neutral

4. **Analyzing Each Option**:
- **Endothermic**: This process absorbs heat, which is not applicable to combustion. Therefore, this option is incorrect.
- **Exothermic**: This process releases heat, which is characteristic of combustion. Therefore, this option is correct.
- **Reactive**: While combustion involves a reaction, it does not specifically describe the heat aspect. Therefore, this option is incorrect.
- **Neutral**: This implies no heat change, which does not apply to combustion. Therefore, this option is incorrect.

5. **Conclusion**:
- The correct answer is that combustion is an **exothermic** process.

**Final Answer**: Combustion is an **exothermic** process.
