Question

Which compares the thermal energy found in a piece of coal with the thermal energy found in a newly opened coal mine?

Answer 1

A.
The amount of thermal energy is directly related to the potential energy of a substance's particles. A piece of coal has fewer total particles than a newly opened coal mine. Therefore, the piece of coal has less thermal energy.

B.
The amount of thermal energy is directly related to the kinetic energy of a substance's particles. A piece of coal has fewer total particles than a newly opened coal mine. Therefore the piece of coal has less thermal energy.

C.
The amount of thermal energy is directly related to the potential energy of a substance's particles. The particles in a piece of coal are more concentrated. Therefore, the piece of coal has more thermal energy than the newly opened mine.

D.
The amount of thermal energy is directly related to the kinetic energy of a substance's particles. The particles in a piece of coal are more concentrated. Therefore, the piece of coal has more thermal energy than the newly opened mine.

Answer 4

8th, but my teacher gives 9th and 10th grade stuff sometimes. :)

Answer 5

Well the answer is really both A and B as thermal energy is a function of both the kinetic and potential energy of the constituent particles. The better of the two answers, though, is B.
