NO, it is the opposite. remember molecules expand when heated
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
cold water is denser than hot water. The same is true of most other substances as well.
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
No, hot air is less dense than cold air.
If you have the same volume of both then there are in cold water more molecules.
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 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.
Water goes down in a cold place because cold water is denser than warm water, causing it to sink. In an airtight place, hot water rises because it is less dense than the cold air surrounding it, creating a convection current that makes the hot water move upwards.
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.
