State whether the following statements are true or false: When a candle burns both the physical and chemical changes take place.

Explanation

To determine whether the statement "When a candle burns both the physical and chemical changes take place" is true or false, we can analyze the processes involved in burning a candle step by step.

### Step-by-Step Solution:

1. **Understanding the Components of a Candle**: A candle is primarily made of wax, which is a solid substance.

2. **Physical Change - Melting of Wax**:
- When a candle is lit, the heat from the flame causes the solid wax to melt.
- This process is a **physical change** because the wax changes from solid to liquid but remains the same substance (wax).
- **Key Point**: In a physical change, no new substance is formed. The melted wax can solidify back into its original form.

3. **Chemical Change - Burning of Wax**:
- As the wax continues to burn, it vaporizes and reacts with oxygen in the air.
- This reaction produces new substances, such as carbon dioxide and water vapor, along with smoke.
- This process is a **chemical change** because new substances are formed during the burning process.
- **Key Point**: In a chemical change, new substances are created that are different from the original substance.

4. **Conclusion**: Since both physical and chemical changes occur when a candle burns (melting of wax is a physical change, and the burning of wax is a chemical change), the statement is **TRUE**.

### Final Answer:
The statement "When a candle burns both the physical and chemical changes take place" is **TRUE**.
