Answer: The minimum temperature at which a volatile material will evaporate into a gas and ignite without the assistance of an external fire source is known as the ignition temperature. A volatile compound becomes extremely deadly when there is no extra ignition source.
The temperature causes combustion because it offers enough energy to ignite the substance.
The ignition temperature of the material will drop when pressure and oxygen levels in the ambient atmosphere rise.
Ignition temperature and flash point are not the same things.
