Answer 1

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

Explanation: total thermal energy depends on both mass and temperature, so the huge cold lake contains more energy overall. Particle speed (average kinetic energy) depends on temperature, so the hotter coffee's molecules move faster.
