Explain the energy transformation that occurs when food is digested. a) chemical energy transforms into mechanical energy. b) electrical energy transforms into mechanical energy. c) mechanical energy transforms into chemical energy. d) thermal energy transforms into electrical energy.

A, is the correct answer.  Food stores chemical energy. Our movement is mechanical energy. therefore Chemical energy transforms into mechanical energy. Happy to help :D

a. the answer is A hope this helps you guys bye

Explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
