Generally, warm water has a lower density than cold water. However, between 1 and 4 degrees C the reverse is true.
cold water?
Cold air is denser than warm air because the molecules in cold air are closer together, leading to higher density. Warm air, being less dense, rises above cold air as part of the process of convection. This difference in density is a key factor in determining atmospheric stability and weather patterns.
Warm air is less dense than cold air because the molecules in warm air have more energy and are more spread out, resulting in lower density. Cold air is denser because the molecules are closer together and moving slower.
A density current is where a warm current floats on top of a cold currentA density current is where a warm current floats on top of a cold currentThe movement of a mass of cold, dense ocean water as it sinks beneath warmer surface water.
Warm air and warm water. Cold air and cold water keep ice cooler longer.
Cold air is denser than warm air because the molecules in cold air are packed closer together. As a result, cold air has a higher density, meaning it weighs more per unit volume compared to warm air. This difference in density contributes to differences in air pressure and can affect weather patterns.
True... warm water is less dense than cold water.
Yes, cold water is dencer indeed
Cold water is more dense than warm water so the cold water has to sink to the bottom which causes a density current.
Cold water is denser than warm water due to its higher molecular density and lower thermal energy, causing it to sink below the lighter, less dense warm water. This process, known as thermal stratification, occurs because the cold water is more compact and heavier, allowing it to displace the warm water and move downward.
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 dye is denser than warm water, so it sinks instead of rising. When cold dye is added to warm water, it stays at the bottom because the warm water is less dense and stays on top. This difference in density causes the cold dye to remain submerged in the warm water.
If you think to density (not weight) hot water is less dense.
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.
The highest density of water is at the temperature of 4oC (ie. 1.000 kg/dm3), above or below this the density is lower.
Cold water with high salinity takes up more volume than warm water than low salinity
