Why is pumice lighter than water?
It depends what kind you have... If its density is less then the water it is floating in, yes.
What is the role of density in turbidity currents?
Density's role is to push the cloudy turbid water under the less dense surrounding water to start the turbidity currents
Where would you find the lowest density in seawater?
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.
If the porous lava rock gravel was placed in water what would happen?
Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.
Wht is the density of oil?
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)
Is very cold water more or less dense than less cold water?
Water is at its greatest density at 4 oC.
Which weighs more cold water or warm water?
If you think to density (not weight) hot water is less dense.
Which is less dense cold air or 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.
Why does your cold water have water flow but hot water has no flow?
It is a matter of density cold water is denser(compact) that hot water. thus cold water will flow faster than less dense(loose)hot water.
Why does hot air or liquid rise?
It will rise because it has less density, so it tends to "float" on the denser, cold, air.The reason it is less dense is because when you heat air, its volume increases. Since density is mass/volume, the density decreases in this case.
How are mass and volume related to the sinking and floating of an object?
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. Density = mass / volume.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. Density = mass / volume.
How is the density in hot water different from that in cold?
Above 4 degrees C, the hotter it is then the less dense.
Which water cold or hot would be denser at room temperature?
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.
Why iron nail sinks in water?
its density is greater than water, so it sinks.
What is the only rock that has less density in water?
The density of an object is constant, therefore, no rock can have less density in water.
How does cold air effect the density of gas?
'Cold' air will have less volume so the density is greater.
Does the temperature of water affect the its density?
The warmer the water is the less dense it is but the colder it is the more dense it is. A2: therefore, warm water rises above cold water
