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.
Answer
We know that,
Density of solid > Density of liquid > Density of gas.
Hence, the order of densities is as follows
Iron > Chalk > Honey > Water > Exhaust from chimneys > Air
