It will always, unless it is the same substance (in the same state) or something of equal density. Something of lower denisty always floats on something with higher.
Oil is less dense than water, so it would float on top of the water in a distinct layer due to the difference in densities.
Saturn would float in a bathtub because it has the lowest density of all the planets. If something has very low density, it floats. Thus explaining why Saturn would float
The outerside would be the Epicardium. The second layer would be the Myocardium. The last layer would be the Endocardium. There is also another layer which completely covers the heart. Its called the Percardium.
Chloroform is denser than water and would not float on its surface. Chloroform has a density of about 1.48 g/cm3, while water has a density of 1g/cm3. When added to water, chloroform would sink and form a separate layer at the bottom.
If you were to go there you would either float...or not float. You choose;)
The ability for something to float on another substance is related to the density and since ice is LESS dense than water it would float on top of water, not water on top of ice.In other words, water is more dense than ice and thus no.
It would depend on the item of course... it would take an awful lot of salt to make a bar of steel float. Likewise, a sealed empty bottle might float on either cold or hot water. However, water will expand when heated, thus reducing the density of the water. Salt will increase the density of the water. It is possible to find some items that would float in cold water, but not in boiling water without compensating with something like salt.
-- It would float in the water, with part of it above the surface. -- It would hang just below the surface, or at whatever depth you placed it. -- It would sink down through the water like a rock.
float
It will float. Its a rock. It actually depends on how much water you have, if you you tried float it in the ocean, it would obviously sink. But if you tried to float it on a gladd or bowl or water, it would float,
Because the fluid at the bottom has a greater density than the one at the top.
Railroad cross ties made out of wood would float. Concrete railroad ties would not float.
