Generally, warm water has a lower density than cold water. However, between 1 and 4 degrees C the reverse is true.
cold water?
The density of all materials is related to temperature; the cause is the thermal expansivity which modify the volume (density=mass/volume).
Warm water has a density lower than cold water.
Cold air is heavier than warm air.
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.
The density between cold and warm air is, cold air is heavier than warm air.
Warm air and warm water. Cold air and cold water keep ice cooler longer.
Not really. Warm air usually has a higher volume than cold air, so its density is usually smaller than that of cold air.
Cold air is heavier than warm air.
Because cold water has a higher density than warm water. Water contracts when its temperature lowers, causing its density to increase.
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.

The density between cold and warm air is, cold air is heavier than warm air.
If you think to density (not weight) hot water is less dense.
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
warm air and cold air are both different pressures and density's!!!!
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.
