Question

how can you determine that a coin is not pure sliver if you know the mass and volume of the coin

Answer 1

Answer:

Through Density

Explanation:

Every metal present on Earth and beyond have a particular density, that is, Density = Mass/Volume

Almost all metals have different densities,

Now silver has a density of 10.49g/cm³ that is if we were to take some silver of mass M then its mass by its volume V will be M/V = 10.49g/cm³

Let it be of any mass, the volume also keeps changing and so density is constant and irrespective of volume or mass.

So if the coin's mass/volume is not equal to 10.49g/cm³ then that means it is either another substance or it is impure.

So using density we can determine it. If you search deep this is the same concept or technique Archimedes used to prove if the Kings crown were made of pure Gold or not.

Hope you understood it........All the best.
