There are two ways:
A stone does not float because it is denser than water, meaning it weighs more than the water it displaces. The buoyant force acting on an object in water is equal to the weight of the water displaced by the object. Since the stone is heavier than the water it displaces, it sinks instead of floating.
Most stones will sink in water because they are denser than water. However, some types of pumice stones are porous and can float on water due to their low density.
no as it normally sinks down when put in water
A stone is more dense and heavier than water, so it sinks. If you were to hollow out the top of the stone into a shape like a bowl, it would then be mostly filled with air, and might float. That is the same idea as with boats - even steel boats float if they are hollowed out to where they are light enough. I have even seen competitions to see who can build the best concrete boat.
A stick can float on water due to its density being lower than that of water. The air trapped within the stick and the porous nature of the wood make it less dense, allowing it to float. This is due to the principle of buoyancy, where an object will float if it displaces an amount of water equal to its weight.
A stone that can float on water is a pumice stone. Ejected from a volcano, and full of holes, it has been known to float.
No. To get them to float they must be placed on something light.

the stone that never sunk in water is pumice. Because of its holes it can float easily across the water.
Diamonds do not float.
A pumice stone is light weight due to numerous trapped gas bubbles that can cause it to float on water.
Same as when these stones were in boat when the stone in boat ,water need more V to make float power the same weight as the stone's. so lower level when these stones are in water.
The molecules in a stone are packed together more tightly than the molecules in water-- the stone is more dense than the water is, so the stone sinks.
Pumice floats on water. It is because it is made out of lava which had bubbles left inside it. The bubbles has air trapped in it. These bubbles allow pumice to float on water.
Yes, adding salt to water increases its density, which can make some objects that would normally sink, like eggs, float. By altering the density of the water, the buoyant force exerted on the object can be increased to make it float.
That depends on the material of which the stone is composed. Some stones are so light that they will float in water e.g. pumice stone, while most others will sink in water.
No, soapstone does not float in water. It is a dense, metamorphic rock composed primarily of the mineral talc, which makes it heavier than water and causes it to sink.
