[Audio] PROJECT ON RELATIVE DENSITY. PROJECT ON RELATIVE DENSITY :-.
[Audio] Density is defined as the substances mass per unit of density its denoted by the letter p or d and it's a scalar quantity its written as p=m\ or unit of density=unit of mass by \ unit of volume its S.I unit is kg m-3.
[Audio] RELATION BETWEEN S.I AND C.G.S UNIT. RELATION BETWEEN S.I AND C.G.S UNIT.
[Audio] RELATIVE DENSITY THE RELATIVE DENSITY OF A SUBSTANCE IS THE RATIO OF THE DENSITY OF THAT SUBSTANCE TO THE DENSITY OF WATER AT 4 DEGREE C Ps/Pw=Ms/Mw or relative density = density of substance / density of water at 4 degree c so it's the ration of the density by density of that same object in water at 4 degree c.
