sinks
The rock that sinks has a higher density than the rock that floats. (The only rock that floats is pumice.) More specifically, for a rock to float it must have a lower density than the fluid it is placed in. This will mean that a given volume of the material will have a smaller mass (and hence weight) than the fluid it displaces. As such the material will have positive bouyancy and will tend to float on top of the more dense material.
Styrofoam floats on water, Soap sinks.
You can determine whether a solid substance is more or less dense than water by comparing their densities. If the density of the substance is greater than the density of water (1 g/cm^3), then the substance is more dense. If the density of the substance is less than the density of water, then the substance is less dense.
because it's density is more than one
No. A toothpick and a tiny stone both have small mass, but one floats and the other sinks. A passenger ferry and a large boulder both have large mass, but one floats and the other sinks. It's not the mass that determines whether the object will float. It's the ratio of its mass to its volume ... the number known as the object's "density".
The question first states that the two objects " ... have the same mass", and then asks "Which one has the greater mass?"This does not compute.Just from the fact that one floats and the other sinks, we can't conclude anything regarding their relative masses, without knowing their respective shapes.Consider all the steel in a battleship being rolled up into a solid ball ...
When two substances mix, but separate with one on the bottom, and one on the top is known as a SUSPENSION mixture. An example of this is oil and water. When mixed, the water settles to the bottom, while the oil remains on top. This occurs because of the difference in density. The substance with a high density sinks to the bottom, while to less dense substance floats on the top.
The one which flow has less density than the water (i.e. 1) means no screws will be there and they will be stuck with some adhesive.The one which sinks has more density than water and screws might be used in it because screws are generally made from iron whose density is more than that of water.
Weigh samples of the two that have the same volume. A solid object with greater "average density" will sink in a less-dense fluid. A lighter fluid will float atop a heavier one if they do not form a solution. Examples: - One cc of metallic iron will weigh more than one cc of motor oil (sinks) but less than one cc of mercury (floats in the mercury). - One cc of mercury weighs more than one cc of water (sinks) but one cc of oil weighs less than the water (floats).
If an item floats, Then it is less dense than the liquid it floats in. One can prove this using bernoulli's equation. To determine the weight of the floating object, take the volume of water displaced by the portion of the object below the fliud surface then multiply that by the density of the fluid. This process gives you the bouyant force on the floating object and therefore the weight. Then take that weight and divide it by the total volume of the. Object to get its density. Also note that if an item is suspended below the surface but. Above the bottom of the fluid body, then the item and fluid have equal density. If the item sinks to the bottom it has higher density than the fluid.
Helium is lighter than air so it floats. Cold air is fairly "heavy'" so it sinks to the bottom Average density of air + baloon is greater than surrounding air so it falls to highest density option ie downwards.
One substance will float on another if its density is less. By adding salt you are increasing the density of the solution. As you add salt, at some point the density of the solution will reach and then exceed the density of the egg
