Steels density is greater than water
Yes, they are.
Yec.
It makes the air less dence it takes the water out of the air
yes polystyrene is ls less dence than water because it floats
No, an object will float if it is less dense than water. If an object is less dense than water, it will displace an amount of water equal to its weight, causing it to float.
Ice is less dense than water. When water freezes into ice, the molecules arrange themselves in a pattern that makes ice less compact, causing it to take up more space and be less dense than liquid water.
Steel is more dense than water because it is made mostly of iron, and iron is much denser than water. The density of iron is 7.874g/cm3, while water's density is 1g/cm3.
cooking oil
corn oil is more dense
The steel boat has more bouyancy because it is mostley filled with air as with the steel ball it is dence and heavy so it sinks
The density of the VOLUME of the ship is less than the density of the water it displaces (pushes out of the way). While the steel of a steel hulled ship is denser than water, the steel plus the air enclosed by the steel is less dense.
Its so that they can see and hear when prey or a predator is near by.
