An object floats if its average density is less than the density of water. An iron nail is a solid piece of iron, and the density of iron is greater than the density of water, so it sinks. An iron ship, despite being made of iron, is designed with a large hollow volume filled with air.

An object floats when the buoyant force equals its weight. A ship displaces a volume of water whose weight is equal to the ship&#8217;s weight, and this displacement is possible because the ship&#8217;s average density is lower than water.<\/section>\n","protected":false},"excerpt":{"rendered":"<p>An iron nail sinks in water whereas an iron ship floats.
