Question

explain why a flickering flame produces smoke​

Answer 1

Answer:

It is because unburned particles escape from the flame.

Explanation:

When you light up the candle, the flame melts the wax near the wick. The capillary action then draws the wax, up the wick. Flickering takes place when flame takes too little or too much air. As a result of it, the unburned carbon particles escape into the air before they could completely combust.

Answer 2

Answer:

Explanation:

The flame uses the hydrocarbon particles in the wax to produce heat, water vapor, light and carbon dioxide.  

A flame flickers when it receives either too much or too little air or oxygen. As a result, the unburned carbon particles are released in the air, as smoke, before they have been completely combusted.
