12. How will you make difference between density and specific gravity of a body?



Specific gravity

The density of the substance is defined as the mass per unit volume of that substance.

Specific gravity of a substance is defined as the ratio of the mass of certain volume of it to the mass of the same volume of water at 4ËšC.

Its unit is kg/m3 or g/c.c.

It has no unit because it is the ratio of same physical quantity.
