Cold water
Hot water is less denser than cold water and has a greater temperature.
Hot water is less denser than cold water and has a greater temperature.
You are wrong ! - Cold water is heavier ( denser ) than hot water.
cold water is denser than hot water. The same is true of most other substances as well.
Cold water is denser then hot water and weighs more so hot water will always stay on top of cold water no matter the pressure in the line or volume unless forced by flow hot water water will always be on top.
NO, it is the opposite. remember molecules expand when heated
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
When cold water is poured into hot water, it sinks because it is denser than the hot water. The cold water is heavier due to the molecules being closer together at a lower temperature, causing it to sink to the bottom. The hot water, which is less dense, rises to the top.
Cold metal.
The reason for this is convection, when the temperature rises the liquid (in this case water) expands, causing it to rise above the cold water which is denser due to the lower temperature. So the hot water rises and the cold water sinks, making a convection current.
The difference in water density (hot-cold) is very small, compared to the difference in density between water of any temperature, and your body. That is, even hot water is more dense that we are, so we still float.
If you have the same volume of both then there are in cold water more molecules.
