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 first discovered by the Greek scientist 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 itself is denser than water (7800 kg/m3 vs 1000 kg/m3), a ship is not a solid block of steel. It is hollow on the inside, which means it contains a lot of air.

3. Effective Density: When considering the ship as a whole (steel plus the air inside), the average or "effective" density of the ship is much less than the density of water.

4. Floating: If the effective density of the ship is less than the density of water, the ship will float. This is because the weight of the water displaced by the ship is greater than the weight of the ship itself.

So, even though steel is denser than water, a ship made of steel floats because it is designed to displace more water than its weight.
