Ken campfire energy transformations took place when the wood was burned?

• A. Heat to Chemical and Light
• B. Chemical to Heat and Light
• C. Chemical to Electrical and Heat
• D. Light to Heat and Chemical

Answer: (B)

When a campfire burns, the energy stored in the wood’s chemical bonds is released through oxidation. That chemical energy is transformed mainly into heat and light: the rapid reactions emit warmth and visible flames as energy leaves the wood molecules and becomes thermal energy and radiant energy. In other words, chemical energy → heat and light. The heat warms the surroundings and the light provides the glow of the flames. The other directions don’t describe what happens in combustion—heat isn’t causing new chemical energy to form, and burning doesn’t inherently produce electrical energy or convert light back into chemical energy.
