Yes.
True... warm water is less dense than cold water.
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Water is at its greatest density at 4 oC.
Yes, generally speaking, room temperature water is less dense than cold water. As water cools, it contracts and becomes denser, which is why cold water is often heavier than warm water.
Warm water is less dense than cold water, so it sits on top of the cold water. This is because warm water molecules are more spread out and have less mass per unit volume compared to cold water molecules, causing warm water to be less dense and float on top of the denser cold water.
As water eats up, it expands. There is still the same amount of water, but now in a larger space so it is less dense than cold water.

Warm water tends to stay on top of cold water because it is less dense. When water is heated, the molecules move farther apart, making warm water less dense than cold water. This difference in density causes warm water to float on top of cold water.
cold ocean waer has more dense than warm water.
Warm water is less dense than cold water.
In hot water the molecules vibrate faster than cold, resulting in the same number of molecules taking up a larger space. This means that hot water is less dense than cold water, and thus floats above the cold water.
