Answer:
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 chimney, honey, water, chalk, cotton, and iron.
Solution :
We can solve this question by keeping this concept in mind that density of solid is more compare to liquid and density of liquid is more compare to gas.
Gas < Liquid < Solid
The given substances in the increasing order of their densities can be represented as:
Air < Exhaust from chimney < Cotton < Water < Honey < Chalk < Iron
