Which of the following situations best illustrates chemical energy being converted to another form of energy?

• A. A candle burning and producing light and heat
• B. Ice melting in a warm room
• C. A ball rolling down a hill due to gravity
• D. A mirror reflecting sunlight

Answer: (A)

Verified step by step guidance

1. Understand that chemical energy is the energy stored in the bonds of chemical compounds, which can be released or transformed during a chemical reaction.
2. Identify which situations involve a chemical reaction where bonds are broken and formed, leading to energy conversion.
3. Analyze the option 'A candle burning and producing light and heat' as it involves combustion, a chemical reaction where chemical energy is converted into light and heat energy.
4. Recognize that 'Ice melting in a warm room' is a physical change involving heat transfer but no chemical energy conversion.
5. Note that 'A ball rolling down a hill due to gravity' and 'A mirror reflecting sunlight' involve mechanical and light energy, respectively, but not chemical energy conversion.
