Energy Transformations

Question 3 • GA-GSE Physical Science B

The human body stores chemical energy from digested food. Some of the chemical energy is converted into mechanical energy when the body moves. Which statement is best supported by this information?

Answer
A
The body does not convert chemical energy to thermal energy.
B
The body does not convert chemical energy to kinetic energy.
C
Digested food is a source of potential energy.
D
Digested food is a form of radiant energy.

Explanation

Chemical energy stored in food is a form of potential energy because it can be converted into other forms of energy. The question says some of that stored energy becomes mechanical energy when the body moves, supporting the idea that digested food is a source of potential energy. Choices A and B are not supported, and food is not radiant energy.
