. The mass per unit volume of a substance is called density

(density = mass/ volume).Arrange the following in order of increasing density -  air, exhaust from chimneys, honey, water, chalk, cotton and iron.


Best Answer


  • Solids are mostly denser than liquids.
  • LIquids are mostly denser than gases.
  • Compared to other materials, air has an extremely low density.
  • Because exhaust from chimneys contains several gases, such as carbon dioxide and carbon monoxide,

as well as microscopic particles ejected as a result of the factory's burning of materials, it has a higher density than air.

Final answer:

The order of increasing density is:

air < exhaust from chimneys < cotton < water < honey < chalk < iron.
