The lake will have more total thermal energy, but the particles in the coffee will be moving faster.

Answer 1

To evaluate the thermal energy and particle movement in the coffee and the lake water, we need to consider the temperature and the volume of both.

1. Total Thermal Energy: The lake, being vast and filled with cold water, has a large volume. Even though the temperature of the water is low, the sheer volume means that the total thermal energy is very high. Conversely, the coffee is much hotter than the lake water, but since it is in a smaller volume, its total thermal energy is less than that of the lake.

2. Particle Movement: Particle movement is related to temperature. Since the coffee is hot, the particles in the coffee will be moving faster compared to the cooler particles in the lake.

Given these factors, the correct statement is:

The lake will have more total thermal energy, but the particles in the coffee will be moving faster.
