Methan burn in air by heating.
No it is not essential. It will burn in air or oxygen if ignited by some spark or match but there are many other ways to get burning in chemistry. The requirements for burning are fuel, oxygen and heat. Oxygen can be supplied by the air for many fires. Heat must often be introduced initially to ignite the fuel but the heat of combustion will then be enough to sustain the burning. Fuel could be methane but there are many other potential fuels in chemistry, for example hydrogen, propane, wood ... Many dry foodstuffs will burn in air if lit.
When you close the air holes, there will not be enough oxygen entering the burner to react with all the gas. As a result the methane cannot burn completely and carbon (soot) remains unburned.
The fact that it oxidizes in air is a chemical property of methane.
The four fuels that burn in air are:Woodcoalgasoil

The three elements that make a fire are fuel, oxygen and heat. The methane is the fuel, oxygen is present in the atmosphere and the flame provides the heat.
1.7 kg air is required to burn 1 kg of nitromethane. AFR = 1.7
Air is not a fuel. Most fuels such as gasoline or methane require air in order to burn, so air, or more precisely the oxygen in air, supports combustion, but it is not a fuel, it is an oxidising agent.
No methane wont burn in oxygen free atmosphere Because you need oxygen to burn Methane. Methane by itself, even in the presence of lightning and comet strikes, is a perfectly safe gas. so methane does not burn in absence of oxygen Vishal Rijhwani
Methane gas settles down because methane gas is heavier than and is carried by the upward displacement of air. ---------------------------------------------- The density of methane is 0,717 g/L and the density of air is 1,2 g/L at 0 0C; consequently methane gas raise in the air.
A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.
Yes methane is lighter than air because it is less dense than air.
A non luminous flame is produced when the air valve is opened enough to allow complete combustion of the methane gas.

the bubble will probably pop before you can even light it Different answer: If the gas inside the bubble is flammable, it will burn... assuming the bubble doesn't pop first. For instance, a methane bubble will burn if you light it, though one filled with regular air will not.
