(Yes/No).
Lighting a matchstick

Answer

**Step-by-Step Solution:**

1. **Identify the Change**: The change we are considering is "Lighting a matchstick."

2. **Understand the Process**: When a matchstick is lit, a chemical reaction occurs. The wood and chemicals in the matchstick react with oxygen in the air to produce heat, light, and combustion products (like ash and smoke).

3. **Determine Reversibility**:
- Once the matchstick is lit, it burns and transforms into ash and gases.
- The original matchstick cannot be restored from the ash and gases produced after burning.

4. **Conclusion**: Since the change involves a chemical reaction that produces new substances and cannot be reversed, we conclude that lighting a matchstick is a change that cannot be reversed.

5. **Final Answer**: No, lighting a matchstick is not reversible.
