Question

explain why a ship made of steel floats on water but a solid of steel sink. cbse physics

Answer 1

Since the density of the solid of steel is greater than that of water, therefore if we place the solid steel (like nails) on the surface of the water the weight of the object (solid steel /nails) is greater than the weight of water displaced by it so it sinks. Whereas the ship made of the same material (steel) doesn't sink because a ship is made hollow from inside which reduces the average density of the ship than that of water. So, a ship floats on water
Therefore even when the small part of the ship is submerged, the weight of the water displaced become equal to the weight of the entire ship. So, the steel ship keeps on floating.

Answer 2

Answer:will float

Explanation:the ship will float but nail sinks because the ship has a huge hollow space inside which air occupies so it's density is greatly reduced but iron nails density is high coz no hollow space
