At What Temperature Does Gasoline Burn?
Gasoline burns at 495 degrees Fahrenheit at standard atmospheric pressure. This ignition temperature is the lowest temperature at which gasoline may undergo combustion. If the temperature is lower than this, a fire is needed to ignite gasoline. If too little air is present, a higher temperature is needed.
Gasoline does not burn when it remains in liquid form. The ignition temperature is required to first cause it to turn into a vapor, after which mixes with air and ignites by exchanging outer electrons with the oxygen present. Gasoline can be turned into a vapor at a much lower temperature, called the flash-point, but it does not burn without a source of ignition.
