Well, its not the steel in the ship that floats exactly, its the oxygen contained in the ship, the more water something displaces means the more water is pushing it in horizontal direction. and because of the shapes of ships causes it to be pushed up.
Steel would sink in Mercury because the density of steel (7.85 g/cm^3) is higher than that of Mercury (13.6 g/cm^3). This means steel is denser than Mercury, so it would not float on it.
No, steel is denser than saline water, so a steel pin would sink in saline water.
Look at a ship for example... It is made entirely of steel but it manages to stay afloat. The steel ships are filled with air which causes the average density to be less than water's density (1.00 g/ml). If you had a piece of plastic it would just sink because the density is more than water.
If a steel ship were not hollow, it would be much heavier and have a higher overall density. This would make it more difficult for the ship to float and it would likely sink. Hollow spaces in a ship contribute to buoyancy and help the vessel stay afloat by displacing water equal to its weight.
A ship displaces a greater mass of water than its volume in water would make up, thereby, it weighs less than the volume of water it displaces and so it floats. A solid steel ball however displaces a lesser mass of water than its volume in water and would, thereby, weigh more than its equivalent volume of water and so it would sink.
it is hollow so it will float
steel will float in mercury
Steel would sink in Mercury because the density of steel (7.85 g/cm^3) is higher than that of Mercury (13.6 g/cm^3). This means steel is denser than Mercury, so it would not float on it.
The number of ping pong balls needed to get a steel cube to float would depend on the mass of the steel cube.
No, steel is denser than saline water, so a steel pin would sink in saline water.
Yes, silver would float in mercury because silver is less dense than mercury. This means that silver would displace an amount of mercury equal to its own weight, allowing it to float on top of the mercury.
Not as long as it's still in the shape of a block. But if you re-shape it into the shape of a cup ... whether round or rectangular ... it will float, because it displaces much more water than a block does. If your cup-shape is done artistically and with care, people may call it what it looks like ... a little "boat" or "ship". Those objects are usually made out of re-shaped blocks of steel.
Nothing

Rubber tires are preferred to steel tires because if we had steel tires driving over the smallest pebble would be a very bumpy ride. Rubber tires are flexible and will be smooth when going over rocks. Not to mention, if we had steel tires the government would have to replace the roads everyday with the amount of people tearing them up with steel tires. Also, rubber tires wear out and that means you will have to buy new ones again..
To find the volume of a small pebble using a measuring cylinder, you would first fill the measuring cylinder with a known amount of water. Next, carefully drop the pebble into the water and measure the new water level. The difference between the initial and final water levels represents the volume of the pebble displaced, which is equal to the volume of the pebble itself.
