Things that are less dense that water float while things that are more dense sink.
An object's density has to be less than what it's floating in. If it's less, the object floats. If it's more, the object sinks.
For more information about buoyancy see the related questions below.
There is an exception to the above density proposal.
Sometime a solid steel object which is more dense than water can "float" on the surface of water.
Solid steel objects are able to "float" on the surface of water due to the surface tension of the water.
Small solid steel objects such as double edged razor blades, needles and even paper clips can float on this surface tension film where water meets with the air above.
The above objects have to be carefully lowered onto the surface of water and they will "float".
To prove they are more dense than water, simply push them under the surface and they will sink to the bottom.
See the related links to see a floating needle and floating paper clip.
Well some do - mineral spirits for example are a hydrocarbon that do float on water. However, others such as methylated spirits are totally water soluble and hence dont float.
What is the word thatWhen a membrane allows some things in but keeps others out
Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.
No, things do not float more on kerosene than oil because both kerosene and oil have similar densities. In general, objects will float on a liquid if their density is lower than that of the liquid.
because th salt makes things float and George bush was the worst president
because of buoyancy!
On some liquids it will float, on others it will not.
Some things float or sink based on their density. Objects that are less dense than the liquid they are placed in will float, while those that are more dense will sink. Additionally, the shape and size of an object can also affect whether it floats or sinks.
Because some objects are heaver than others.
no because some things are denser then others and might sink for ex:Rock,shoe,cookin pan and ecc.
ice
The buoyancy of an object determines if it will float or sink. Objects with a density less than that of the fluid they are placed in will float, while objects with greater density will sink. Additionally, the shape and size of an object can also affect whether it floats or sinks.
@it's called buoyancy because some things are heavier than others .......................... that is a good theory but no, buoyancy does cause it but buoyancy also needs air pressure took keep afloat .
Because of the objects density.
Because some objects are a lot denser than water so the sink and others are less denser so they float
Some olives float while others sink is due to the amount of brine they take on during the curing process.
It is quite common for various things to float in water. But any liquid can cause things to float.
