I have to get this done today 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 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.C.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.D.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.
