Answer 2

Hi Gladroy!
Your's is an interesting question. Fire is complete combustion of the fuel. i.e. It takes up oxygen and forms the completely oxides form of the fuel. Consider the combustion of gasoline or LPG. It hardly produces any smoke, as it is fully oxidized. The products should be carbon dioxide and carbon monoxide (both of them are colorless). When you extinguish fire, you stop the supply of oxygen. So, instead of burning completely, it remains as carbon or higher forms of carbon. Carbon, of course, you know, is black. And this is what happens when you extinguish fire. Guess you are convinced.

Answer 3

black

Answer 4

White smoke is a steam.
Black smoke may be some coke (carbon) that come from incomplete combustion
White + Black is Gray... : )

Answer 5

Its due to incomplete combustion ie carbon shd get enough oxygen to produce CO2 for a complete combustion if not incomplete combustion occurs and CO is produced which creates smoke.

Answer 6

when fire extinguished some gases releases from it and they convert into smoke.
