Why does an iron nail float on mercury while it sinks in water?
Answers
As we know,iron has high density.If we compare the densities of both Mercury and water,we will assume that the density of mercury is usually higher than that of water.Hence,the magnitude of buoyant force given by mercury is also greater.On the other hand,downward pull of iron nail due to gravitational force is lesser than the upward force given by mercury,hence iron nail floats on it.But this is contrasted to water.That is why an iron nail floats on mercury but not on water.
If you have any doubt,comment on the above answer.Also,if you please the answere,mark me as brainliest.
Answer:
An iron nail floats on mercury because the density of mercury is greater than the density of iron. But the density of water is less than that of iron so it sinks in water.
