fresh water is more dense than hot water and this is just a guess from a sixth grader SO DON'T JUDGE ME!!!!
cold ocean water is more dense than warm water
Water is more dense the colder it becomes. It is also more dense the saltier it becomes.
Cold water is more dense.
Ice water is more dense than warm water.
cold ocean waer has more dense than warm water.
Cold salty water will be the most dense.
Cold salty water will be the most dense.
Cold salty water will be the most dense.
The warmer the water is the less dense it is but the colder it is the more dense it is. A2: therefore, warm water rises above cold 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 gets colder it eventually becomes ice. So judging by that, as water gets colder the water gets denser to the point of being a solid. Cold water is more dence than warm water. Ice is less dense than water (which is why it floats) so... but I think the above is still correct.
If you think to density (not weight) hot water is less dense.
