Question

Why does not a ship made of iron sink in water, while an iron nail sinks in it?

TNSCERT Class 9 General Science Ch 7 Liquids

Answer 1

This is because ship is having hallow in it.Thats why it doesn't sink when iron ship is hollowed ship density is less than density of water.. where as iron nail is not hollowed hence it doesn't float on water. when the density of an object is greater that density of water it will sink..where as if density of water is less than density of object it float ... This is archemedics principal... boyance force.....
Thanks for question
