Question

Explain the meaning of the statement ‘relative density of lead is 11.5. Write any one difference between density and relative density

Answer 1

Relative Density = Density of water

Density of a substance

∴ Density of lead = 11.3×1×10

3 kgm

−3

(∵ Density of water = 1×10

3 kgm

−3

= 11.3×10

3 kgm

−3

= 1.13×10

4 kgm

−3

DIFFRENCE BETWEEN DENSITY AND RELATIVE DENCITY

Density is mass of the object per unit volume. Relative density is the density of a body with respect to another. Simply, density=mass/volume.
