In a calorimetery experiment, a researcher may burn a sample of food, which heats a sample of water. This procedure

illustrates which energy transformation?

A. gravitational potential into kinetic

B. chemical potential into thermal

C. electric potential into gravitational potential

D. elastic potential into chemical potential

the answer is B

D. elastic potential into chemical potential

Explanation:

A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature.
