The ship is made of steel.The density of steel is 7800 kg / m 3 and the density of water is 1000 kg / m3 .Explain why the ship floats in the water.

The reason why a steel ship floats in water is due to the principle of buoyancy, which was discovered by Archimedes. Here are the steps to explain this:

1. Buoyancy: When an object is placed in a fluid (like water), it experiences an upward force called buoyant force. This force is equal to the weight of the fluid displaced by the object. This is known as Archimedes' principle.

2. Displacement: A steel ship is designed to displace a large volume of water. Although steel is denser than water, the ship is not a solid block of steel. It is hollow on the inside and contains air, which is much less dense than water.

3. Average Density: The average density of the ship (including the steel and the air inside it) is less than the density of the same volume of water.

4. Floating: If the average density of the ship is less than the density of the water, the ship will float. This is because the buoyant force (upward) is greater than the weight of the ship (downward).

So, even though steel is denser than water, a ship made of steel floats because it is designed to displace a volume of water that weighs more than it does.
