Question

Which statement about the density of warm water is most likely correct?

Answer 1

Option b. warm water is less dense than cold water.

It is due to the the effect of heat on water molecules that's why warm water tend to rise above cold ones. The molecules of the water are excited by the energy. They begin moving faster, so when they bump into one another, they bounce further away. The increase space between the fast-moving molecules decreases the density.
