Question

How does a heavy iron ship float on the water and does not sink because of it weight?

• A. Density of iron ship is less than the density of water
• B. Density of iron ship is more than the density of water
• C. Density of iron ship is equal to the density of water
• D. Density of iron is less than the density of water

Answer 1

The correct option is A

Density of iron ship is less than the density of water

Density of iron is greater than that of water but the ships made up of iron do not sink. This is because the ship is hollow and the empty space in it contains air, which makes average density of the ship less than that of water. Therefore, even with a small portion of ship submerged in water, the weight of water displaced by the submerged part of ship becomes equal to the total weight of the ship and therefore it floats.
