The correct Answer is:
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**. ---
