Question

3 multiple choice 1 point when you burn a log in your fireplace, you are converting electromagnetic to chemical chemical to thermal energy chemical to nuclear energy proteins to amino acids thermal to electromagnetic energy clear my selection

Explanation:

Burning a log involves a chemical reaction (combustion) where the chemical energy stored in the log (from its chemical bonds) is released as heat (thermal energy). Let's analyze each option:

• "electromagnetic to chemical": Burning doesn't convert electromagnetic to chemical energy; this is reversed from what happens.
• "chemical to thermal energy": Correct, as combustion of the log (chemical reaction) produces heat (thermal energy).
• "chemical to nuclear energy": Burning is a chemical reaction, not a nuclear one, so this is incorrect.
• "proteins to amino acids": This is digestion/breakdown of proteins, not burning a log.
• "thermal to electromagnetic energy": Burning produces thermal energy, not the reverse.

Answer:

B. chemical to thermal energy
