Answer:

So, to answer your question, let me tell you the property of density.

So, what is density?

Ans. Density is nothing but how much space an object or substance takes up. This is influenced mainly by how closely the molecules are packed and how hollow or filled is an object, or how many molecules an object posseses.

Explanation:

So, following the defenition of density, let us answer your question:

Why does an iron needle sink while a ship Floats?

Ans. This is due to the fact that though a ship is way more larger than an iron needle, it floats due to the fact that is hollow( filled with air) . So, since it is filled with air inside, it floats in water, wheras an iron needle is not hollow, but it is fully filled with iron, thus its density is more than the ship. That is why an iron needle sinks while a ship Floats.

Answer 2

$\red{ANSWER}$

A needle sinks in water because the weight of water displaced by it is less than the weight of needle .AND an iron ship is shaped that it can displace a large volume of water.The weight of the water displaced by the immersed portion o the ship is equal to the weight of the ship hence it can float. According to the law of floatation a body floats in a liquid when the weight of the whole body is equal to the weight of the liquid displaced by the immersed portion of the body.
