Objects whose average density (weight for size) is LESS than water will float, and will displace only the volume of water with a weight equal to its own weight. This is called "buoyancy." Substances like oil that are less dense will also float atop the water.
Objects whose average density is, or *becomes* greater than the density of water will sink. Its buoyancy is not enough to prevent it from displacing the water and sinking, typically to the bottom. Dense substances like rock or metal also sink rather than float.
Steel boats contain large air spaces below their waterlines. This makes their overall density less than water, even carrying heavy cargo. If, however, the boat springs a leak, and water takes the place of the air, the overall density increases and the boat may sink. A speedboat with foam between wooden hulls might not be able to sink at all, as the wood and foam (both less dense than water) might keep it afloat.

What substances will float in water?
oil
Why don't mostsubstance float in air if they float in water?
It is waters greater density than air that allows some substances to float on water.
Why does sand oil and maple surup sink in water?
more dense substances sink, less dense substances float. oil will not sink in water, it will float, it is less dense.
What are the substances that float in water?
not me thats for sure i love first
Does adding certain substances to water make boats float better?
Yes, if it makes the water denser, the boat will float easier. For example, it is easier to float in salty water.
Which soild substances will float in water?
Wood and styrofoam, to name two.
Why do most substances float in air if they flow in water?
I suspect that "flow" is meant to also be "float", but even with that substitution, it just changes the question from nonsensical to counterfactual.Most things that float in water do not float in air.
What can float on water?
Any object with a density lower than 1 g/cm3.
Does fire float on water?
Many combustible substances (substances that will burn) are lighter (less dense) than water and will float - paper, wood and gasoline are a few examples. When ignited (set on fire), these substances will continue to float, and so will the fire.
Will objects with densities higher than water sink or float?
Objects with higher densities than water will sink in water. What they do in other substances depends on the densities of those substances.
How do you separate gravel and sawdust?
If you think about it, you can figure it out. Does one of the substances float in water and the other one sink?
When milk is mixed with gasoline which substances will float?
The fats (i.e. cream) from the milk will dissolve in the gasoline and the the resulting gasoline/cream solution will float on the water from the milk.
