If you use ice and two compounds, where the ice floats in compound A and sinks in compound B. The ice floats in compound A because the compound has a greater density than the ice' and sinks in compound B because the compound has a lesser density than the ice.
A very interesting phenomenon.
When a body is put on the surface of water, first its bottom surface gets a little bit immersed. So an amount of water vacates from its place to give room for that small portion of the body to occupy the same.
If the weight of that displaced water is very less compared to that of the body, then a larger portion can go into the water and more volume get displaced.
Yet, the displaced water weighs less than the body, the body can immerse further.
This process goes on. Now three cases.
First case: Even the whole body get immersed inside water, the weight of the displaced water cannot exceed the body's weight, then sinking occurs. The body goes to the bottom of the container.
Second case: If on the way, if the displaced water has equal weight of the body, then the body starts floating on the surface with certain portion immersed and remaining still in the air.
Third case: At the time the whole body get immersed, if the weight of the displaced water becomes equal to that of the immersed body, then body floats within water.
So density criteria does not finalize the fate of sinking or floating. Only the comparison of weights of displaced liquid and the body would give the right conclusion.
That is why, steel ship, even it has larger density than sea water, never sinks as the design of the ship is in such a way that the weight of the displaced liquid is very much greater than the weight of the ship itself.
Find a solid (over the temperatures required) substance with a specific gravity slightly greater than 1.0, also with a coefficient of thermal expansion large enough to cause the sinking object to expand (and thus acquire a specific gravity of <1.0 at the given temeprature) when heated. Obviously the temperature at which the object acquires a specific gravity of <1.0 must be less than the boiling point of the water providing the bouyancy.
Some objects float on water because these objects are lights and some objects sink in water because these objects is heavy
all objects float or sink in any liquids depending upon the specific gravity of object versus liquid. if the object has higher specific gravity,it will sink &otherway.
It has to do with how dense things are. If it is equal to or less dense than water, it will float. If it is greater, it will sink.
scoria will sink but pumice will float.
Octane float on water.
It will sink, it is very dense
This depends on the density of this item: more denser than water-sink, less denser than water-float.
Because not sink on top!
no!!
I have a marker which float in water.
Its density.If a substance is denser than water, it will sink. If it is less dense, then it will float.(The surface tension of water also contributes slightly to this.)
Whether things float or sink this depend only on the density , the density of the salt water is aprox. 1030 kilogram per meter cube so if you but things have density less than that they will float , things with higher density sink.
does Arsenic float or sink
it will float as long as it is not fully covered water.
scoria will sink but pumice will float.
Yes and no. Rubber bands can float and sink in water. They will float on the water for awhile and then will sink. But not all the time the rubber bands will float on the water for awhile. Sometimes it will immediately sink.
float
Float.
Objects sink or float depending upon their densities. For example wood floats on water because the density of wood is less than that of water, while a piece of iron would sink in water as its density is more than water.
Hmmm. Canned/Tinned fruit will most certainly sink. Most fruits straight off from the tree will float. However, if the fruits are not ripe, they might sink as they are very dense. A coconut will most certainly float. A packet of biscuits (unopened) will float for a long time. Oatmeal flakes will float for a while, then sink to the bottom. Potatoes and carrots will sink. Lettuce and cabbage will float Regards.
