If it has enough surface area such as a leaf or bigger yes so long as it lands on the water in such a way it traps a little air under it, note..even concrete can float, many septic tanks are made of concrete and will float in only about a foot of water if you dont remember to fill them with water before it rains
the volume of the puri get light weighted and it float on water
No, it isn't hollow/light enough... Improving answer: But sometimes things don't actually "float" on the water when they are really held up by surface tesion. I have heard that you can make paper clips or pins "float" on the surface of calm water.
Well not all organs can float, but lungs can float on water
Freshwater is less dense than saltwater, and so it tends to float on top, as less dense things tend to float on denser things.
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
They weigh less than the water they displace.
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.

It is quite common for various things to float in water. But any liquid can cause things to float.
It's light enough to float on water
ghfghv
things that float in water
No. To get them to float they must be placed on something light.

salt makes the water denser, so things that are now less dense than the salt water will float
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
