Why does a lighter not explode when lit?
There are two things at play: First: The butane which burns is pressurized inside the lighter, it is expelled at such a rate that it only mixes with enough oxygen that it can ignite a few milometers above the nozzle. Second: There is not enough oxygen inside the lighter for combustion to occur in…
The Short Answer
There are two things at play: First: The butane which burns is pressurized inside the lighter, it is expelled at such a rate that it only mixes with enough oxygen that it can ignite a few milometers above the nozzle. Second: There is not enough oxygen inside the lighter for combustion to occur inside. Think about it like this, if you have a spray bottle and fill it with gasoline, then spray a fine mist of gasoline into the air near a flame, that small cloud will ignite in a fireball. However; if you have a sealed container filled to the brim with gasoline, and somehow get a spark to go off in that container, the gasoline will not ignite. Gasoline requires like 100 parts of air for every 1.5 parts of gasoline before it will ignite. Butane is roughly the same. Here is a wiki on flammability limits: _URL_0_
