Distinguish Between Density and Relative Density. - ICSE Class 8 - Physics

ConceptConcept of Flotation and Sinking of a Substance (Relate to Density)

Question

Distinguish between density and relative density.

Solution

 Density Relative Density 1 .it is ratio  of mass to volume . D=(Mass )/(Volume)=m/v It is  the ratio of density of substance to 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
