True... warm water is less dense than cold water.
It depends what kind you have... If its density is less then the water it is floating in, yes.
Density's role is to push the cloudy turbid water under the less dense surrounding water to start the turbidity currents
Answer 1) At the Surface. Answer 2) I disagree with the above answer. For practical purposes water is not compressible. Therefore the density is the same all over. The difference in density at the surface and at the bottom is so small that it is negligible. However, fresh water is less dense than seawater, since the salts dissolved in the seawater makes it more dense. For that reason, if you consider seawater near the mouth of a river, that water will be less dense than the seawater in general.
Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.
There are different densities of oils used in cars. It's known as 'viscosity'. In engine oils this ranges from 5 to about 30. Some gear oils, as in back axles range up to 85 or more (this is very thick and dense)
Water is at its greatest density at 4 oC.
Cold water has a higher density than warm water, which causes it to have less volume for the same mass. This is because the molecules are closer together in cold water, making it more compact.
If you think to density (not weight) hot water is less dense.
Hot water is less dense than cold water, which means it displaces less water and therefore produces less upthrust. The buoyant force of hot water is weaker compared to cold water because of its lower density.
Generally, warm water has a lower density than cold water. However, between 1 and 4 degrees C the reverse is true.cold water?
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 air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
Above 4 degrees C, the hotter it is then the less dense.
good try,but water at room temp. has the same density. Unless you boil water and compare,my research shows boiled water has less density.
'Cold' air will have less volume so the density is greater.
An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water.

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.
