Question

why air has less density from exaust of cheminy if air is mixture of all surrounded gases including exaust of cheminy​

Answer 1

Answer:

Explanation:

Exhaust from chimneys < air

Exhaust from chimneys contains hot gases, they are lighter than air. So they rise upwards. Therefore density of gases released from chimneys is less dense than air.

Liquids are denser than gases. So density of water will be more than air. Also honey is a thick than water if added to water it sinks. This indicates that density of honey is more than water.

Solids are denser than liquids. Among solids, cotton is less dense while iron has maximum density.
