Question

an iron nail sinks in water while iron ship floats on water . explain the reason.​

Answer 1

A ship floats on water because buoyancy

there are two factors which influence buoyancy

1.density of the fluid

2. volume of the body

In the first case there is a lesser volume

So it sinks

In the second case, ship has a high volume when comparing the iron nail

So it floats

Answer 2

Answer:

It is the density of an object that dertermines whether the object will sink or float in water. Objects with lesser density than water will float on the surface whereas objects having density more than that of water will sink. As most of the space in the boat is taken up by air so it causes the overall density of boat to be lesser than that of water. Whereas, the density of the iron nail is more than that of water. Due to this the iron nail sinks while the boat floats on the surface of the water.
