Choose the two that apply.

A. The Law of Conservation of Energy applies to these transformations.

B. The chemical energy in the logs is lost during the transformation.

C. The fire is hotter than the logs were, so energy is gained in this transformation.

D. The amount of heat and light energy released equals the amount of chemical energy that is burned.
