which is more density an iron nail or a piece of wood
Answers
iron nail
Explanation:
iron nail is more than that of piece of wood
cause when we compare the densities of two substances, we compare the masses of two bodies of same volume. Thus, the idea of relative density comes to our mind.
Question : which is more density an iron nail or a piece of wood.
Answer : an iron nail
explanation : first understand the meaning of density.
density is the ratio of mass and volume of any substance. it is an intensive property of matter. means, it can't be changed by changing shape and size of any substance. it will remain same.
here we have an iron nail which is definitely very small thing but as we explained, its density is as same as density of a big iron rod or piller. density of iron approx 7.874 g/cm³
and anither is a piece of wood, wood has very low density. its density is even lower than density of water. approx 0.2g /cm³ is its density but you know density of water is 1g/cm³. that's the only reason wood doesn't sink in the water.
therefore the above explanation, it is clear that density of an iron nail is more than density of a piece of wood.
