Question

I have to get this done today 

Answer 1

It is simply a question of the amount of water contained, a lake is much bigger than a pool. The energy ratio is just the ratio of the masses of water concerned. Thermal energy is the total kinetic 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.
