Warm water is lighter than cold water because the molecules are more active in warmer water and evaporation is taking place more quickly than in cold water.

If it gets gradually less dense when it gets warmer or colder.

Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
What is more dense cold or warm ocean water?
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.
Is zinc less or more dense than water?
zinc is more dense than water
Is a magnet more dense than water?
a magnet is more dense then water
Is chlorine less dense or more dense than water?
more dense
What is more dense cold water or warm?
cold ocean water is more dense than warm water
Is warm salt water more dense than cold salt water?
Cold water is more dense.
Is cold ocean water more dense than water water?
more dense
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Is hot water less dense than cold water?
Yes, because the higher the temperature, the faster and more spread out the molecules, therefore making hot water less dense than cold water.
Is Antarctic Bottom Water more dense than Antarctic Intermediate Water?
Yes. It is more dense and colder -- the most dense and most cold of any ocean water on Earth.
Is very cold water more or less dense than less cold water?
Water is at its greatest density at 4 oC.
Why are cold ocean water currents more likely located at deeper depths than warm water currents?
cold water is more dense and sinks i think
Why does cold water in a tube sink to the bottom of room temperature water?
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
Is warm or cold water denser?
its according to what other temperature of water you are comparing it to. water is densest at 4 degrees C so water that is colder then 4 degrees C is technically less dense then water at 4C. in that case the warmer water is denser. but if you mean warm water to be >4C and cold water to be colder then warm water, but not below 4C, then cold water is more dense then warm water. but the question you are probably trying to get answered would have an answer of cold is denser
Is oil more dense than water?
no, oil is not more dense than water
How would this cold water cause a density current?
Cold water is more dense than warm water so the cold water has to sink to the bottom which causes a density current.
