Which statement is correct?
Cold water is more dense than warm water so it sinks to the bottom of the pool.
Warm water is more dense than cold water so it rises to the surface of the pool.
The molecules in cold water have more kinetic energy than the molecules
in warm water so
they move to the bottom of the pool faster.
The molecules in warm water are closer together than the molecules in cold water so they
rise to the surface of the pool.​
