Cold water
yeah cold water is denser than room temperature (warm) water.
Cold Water. Water expands when it freezes, which makes ice less dense.
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.
Cold water is generally denser than warm water, but when compared to salty water, the density depends on the specific temperatures and salinity levels. Salty water is denser than fresh water due to the dissolved salt. Therefore, if the cold water is fresh, it will typically be less dense than salty water at the same temperature. However, if the cold water is very cold and the salinity of the salty water is low, it might be denser than the salty water.
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.
cold water is denser than hot water. The same is true of most other substances as well.
You are wrong ! - Cold water is heavier ( denser ) than hot water.
Bottom, because cold water is denser.
NO, it is the opposite. remember molecules expand when heated
The cold dye did not immediately rise into the warm water because of the difference in temperature. Cold liquids are denser than warm liquids, causing the cold dye to stay at the bottom initially. As the dye warms up, it becomes less dense and starts to rise through the warm water.
