Question

Which example represents a transformation from potential energy to kinetic energy and finally to chemical energy without any other transformations?

A. Maribeth walks outside and pulls her trash can to the front of her house.
B. Kelly’s father lights a firework that soars into the air and explodes with a loud popping noise.
C. Derrick is driving his car to work when the engine stops, and he has to pull to the side of the road.
D. Chad takes an apple out of the refrigerator and takes a bite so his body can digest it.

Answer 1

Answer: B. Kelly's father lights a firework that soars into the air and explodes with a loud popping noise.

Step-by-step explanation:

A firework contains chemical potential energy. When it is lit, that potential energy becomes kinetic energy. Finally, when it explodes in the air, that is a chemical reaction, giving us chemical energy.

B. is the only answer that fulfills all criteria.
