Anything that floats in water, including oxygen, helium, virtually any gas, bread (unless it's balled up), a piece of paper.
These things are all less dense than water.

When comparing the density of a solid or a liquid to the density of water what is the ratio called?
Some folks in the lab call it "spee gee" which is slang for specific gravity (SG). It's relative density, the density of liquid - or any given substance - to the density of water. Surf the link. The formula for density is D= Mass/Volume.
Which of the following is a characteristic of nonmetals?
- lower density- lower hardness- lower melting point- lower boiling point- some nonmetals are gaseous or liquidsetc.
Does the amount of water effect its density?
The only way to change the mass of water would be to either add more of it (which wouldn't change it's density - density is an intensive property, not extensive) or to change the isotopes of hydrogen and oxygen in the water - thus getting "heavy water" such as is present as an intermediate materiel in the refining of tritium and as a moderator in some nuclear reactors.
Do metals have low density?
It varies. Many metal have high density. In fact, the metals iridium and osmium are the densest substances known to man. However some metals are light. Lithium and sodium are even less dense than water.
Does wood float on kerosene?
Sorry if this doesn't help, but it sort of depends on the density of the oil. If oil A has a density lower than oil B, A will float on B. Calculate the density by doing mass divided by volume. If it is under 1 it will float on normal water. If more it will sink.
Why do some things float and why do other things sink?
The object which have more density than water it sinks and which have lower density than water it floats.
Why do some item float higher on the water than other?
It depends on the density on the item. The density of water is 1.0 so if the density of the item is lower then that it will float, if the density is greater then that, then the item will sink.
Will a rock float in water why is it density?
Yes some rocks can float in water. And its determind by density because water density is (8 lbs per gallon and 1 gram per ML) If a rock is lower density then water it floats.
What makes some matter buoyant?
If the object or matter has a density lower than water does.
Why does some things float on water while others dont?
Some objects will float on water as the density of the object is less than that of water. Conversely, if an object is more dense than the density of water, then it will sink.
What makes some things float?
Density of the object and buoyancy of the water/liquid.
When an object sinks its denser than water?
Yes. Water has density of 1 g/mL. If an obct has a density lower than that, it will sink. some objects, however, will float under water.
What are the reason why some things float in the water?
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.
Why do things float?
Because they are less dense than the water. We call the amount of mass in a given volume of space the density. For instance, we could measure the mass of some fresh water in a container. We would then divide the mass of the water by the volume of the container to find the density. However, if we filled the same container with salt water, it would have more mass because the ocean water has the mass of pure water plus the mass of the salt. Since there is more mass in the same volume, ocean water has a greater density then fresh water. For something to float, it must have a density that is less than in what it is floating in. It may seem odd that an enormous ship can float when steel is denser than water. However, if you look at the entire ship you see that there are many places filled with things less dense than water, like air. This means that the density of the entire ship is less dense than that of the water it floats in. To understand why things less dense then water float in water go to the question "Why do some things float but not others?" in the Related Questions section below.An object floats because it is less dense than whatever it is floating in.
What are two ways to compare the density of a unknown substance?
One way is using the formula D=m/v. Or you could get some water and put the substance inside the water and see if the density is lower or higher.
Why do some things float?
They are less dense than water. More dense things sink. Density refers to how tightly the atoms are packed.
If you poor out some of the water in a bucket does the remaining density of the water change?
If you poor out some of the water in a bucket does the density of water change?
