C because warm water is actually denser than cold water

"Warm water is denser than cold water. " - is false

Explanation:

Because cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.
