Distinguish Between

Distinguish between density and relative density.

#### Solution

 Density Relative Density 1. It is the ratio of mass to volume. D=("Mass" )/("Volume")=m/v It is the ratio of the density of a substance to the density of water. 2. Units are g cm^-3 or kg m^-3 It is a pure quantity. It has no units. 3. Density in kg  m^-3=R.D × 1000 R.D = Density in g cm^-3 R.D=("Density in kg" cm^-3)/1000
Concept: Buoyancy Force (Upthrust Force)
