what makes butane in lighters turn into gas when you press the button?
603960
The butane has a boiling point well below room temperature, the only reason it stays liquid inside the lighter is because it's under pressure.  When you push the button you are opening a small hole in the container and a small amount of the butane will boil off and escape through the hole.

There are several ways. For example, burning it directly (mass incineration) or heating it withoug air so that it produces burnable gas (gasification) that can be the fuel to a turbine or reciprocating engine. You can also put it into a tank and let bacteria decompose it. This generates again gas that could be burnt.

Petroleum fuels are made of Hydrocarbons (molecules made up out of Hydrogen and Carbon).  When you combust/burn a Hydrocarbon in excess Oxygen you produce Carbon Dioxide and Water (incomplete combustion also produces Carbon Monoxide).\n\nTake gasoline for instance, mostly Octane (C8H18), the reaction shown below is the complete cobustion reaction which occurs,\n2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O\nThe fuel is chemically changed into Carbon Dioxide (which is not considered a fuel) and Water.  If we assume complete combustion, there is no fuel left over.\n\nIf you were to split up the Carbon Dioxide (or in your case CO that is produced through incomplete combustion), you will obtain elemental Carbon and Oxygen gas.  Carbon could be considered a fuel since it could then undergo further combustion with Oxygen however, it is not a Hydrocarbon fuel since it has no Hydrogen (all the Hydrogen went into water).

Gasoline is ignited by the spark plug, which causes a small explosion in the motor. The explosion causes pressure, which moves the piston, which moves the crank, etc.

gasoline is obtained from the fractional distillation of crude oil.  It is therefore a hydrocarbon.  It is evaporated and mixed with air and forced into the cylinder where it burns.  When the C--C and C--H bonds are broken, energy is required but then more eneryg (than is required to break these bonds) are given off on the formation of H--OH (water) and O--C--O (carbon dioxide)bonds.  This is the thermal energy that causes the burned gas in the cylinder to expand thus forcing the piston away from the spark-plug end, causing the engine to "run"

Under high pressure, the helium is liquified.  The tank is then attached to the pressurized tank and helium simply pours into the tank via gravity.  When the tank is opened, atmospheric pressure converts it back to gas.

Uh...because smoking causes cancer...and gasoline smells funny, I bet if we mixed hot cigarettes and gas fumes, we could start a fire. (gasoline will not ignite from heat alone, It needs to be fumed or misted with a spark or open flame to ignite.) And I agree with everything all the people up above said, its just not a good idea.

Flame, as opposed to fire, is primarily a plasma, which means that it's a gas in a an excited state. As a substance burns the heat produced causes it to vapourise. As a result solids and liquids don't strictly burn, rather it is the gas evaporating off them that burns. \n\nAs the gas starts to burn it starts to break down into chemically smaller components. As a reuslt of the breakdown the electrons within the gas components become excited and unstable. As they collapse into more chemically stable forms like carbon dioxide the gases lose that excited state in the form of radiated energy that we detect as light and heat. \n\nAs a rsult we see flame as a bright light, sense it as being hot and see it flicker and waver, since it exists as a gas in air. It also only exists for a relatively short distance above the burning substance because the chemcially excited form only exists for a relatively breif period.

i have never released the pressure before refilling my butane lighters- if possible, turn your flame as low as it will go, and hold straight vertical. you want to come straight down on the valve, so you dont break or bend it(lighter.)my husband fills lighters with several short "bursts"of butane, but i usually just do 1 to fill. what may be happening is that the butane is leaking right back out of lighter, so what you might want to try is, after filling, flip the lighter back  right side up, and ALWAYS wait until lighter is no linger cold to the touch before trying to ignite. i hadn't had any luck with butane refillable lighters until just here recently, so i can feel your frustration. hoppe this helps!!

The heat of the flame melts the wax. The wick will transport liquid wax into the flame zone (by capillary action), where it can evaporate. The flame consists of two different zones, an oxygen-rich outer layer where carbon monoxide burns with a transparent blue flame and an oxygen-poor inner core where soot particles give off the warm orange glow of a candle flame.\n\nChemically, you have a reaction of the wax (esters of fatty acid) with the air oxygen, forming carbon dioxide and water, and depending on the quality of the wick, soot from incomplete combustion.

it smells like a light version of gasoline. A lot of people still use it to heat their homes.\n\npour from can, light a match\n\ndelayed reation...\npour on floor. Place candle on pool, light candle, when it burns to the bottom, it will ignite the kerosene.

react ... water gas that is carbon monoxide and hydrogen gas in presence of zinc oxide and Cr 2 O 3 under 200 atm pressure and 450 degree celcius temperature result will be  methanol .. this process is done on industrial scale as well first the purification and then the compression takes place and into the reaction chamber condensed and got the result ... ok wish u best of luck

In an oil filled transformer Bucholz gas is generated when an arc or arcing fault occurs. The gas generated collects in a gas relay on top of the transformer and will either cause an alarm as small amounts of gas are evolved. The relay has a second set of contacts that operate should an explosion occur.\nIf you are getting buchlolz gas out of the unit it can only be caused by a  genuine internal fault.\nYou have the makings of a catastrophic failure THE TXFMR MUST BE DEENERGIZED and detanked immediately
