Question
A fisherman in a boat is drinking a cup of hot coffee. The large lake below his boat is full of cold water. Which statement is an accurate comparison of the lake water and the coffee?(1 point)
Responses
The lake will have more total thermal energy, but the particles in the coffee will be moving faster.
The lake will have more total thermal energy, and the particles in the lake water will be moving faster.
The coffee will have more total thermal energy, but the particles in the lake water will be moving faster.
