Question

An iron ball sinks whereas a ship made of iron floats in water , How and Why ?

Answer 1

Floating or sinking of an object depends on weight of the fluid the object displaces(archemedis principle). It states that the buoyant force offered by a fluid on an object is equal to the weight if the fluid displaced by it. A ship has a huge base and displaces a large amount of water and hence experiences a large buoyant force whereas an iron ball displaces a relatively less amount of water and hence it experiences a relatively less force. Hence the ship floats whereas the ball sinks.

This can be understood in another way as well. All those objects which have a density higher than that of the fluid will sink in it and the objects having a lower density will float.

hope this helps ☺️

Answer 2

⏺heya friend !

✴ here's your answer :-

〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰〰

➡basically this all is the result of change in densities of the two things.

✔iron ball has overall a higher density than water , so it tends to sink in water.

whereas,

✔in case of a ship made of iron, which is made hollow from the top and air surrounds it , the ship's average density decreases than water, so it does not sink in water but tends to float on the surface of water .
