How does the thermal energy of a swimming pool compare to the thermal energy of a lake at the same temperature?

A. Thermal energy is the total kinetic energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool.

B. Thermal energy is the total potential energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool.

C. Thermal energy is the total potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger.

D. Thermal energy is the total kinetic energy and potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger.

I believe the answer is C it makes more sense then any of the others.
The lake being spread out has nothing to do with it. So that eliminates A and B. and D doesn't really make sense to me. So you are left with C:)

Hope this helped:)
