It basically depends upon the saturation of hydrocarbons.Alkanes generally burn in air with a blue flame because %age of carbon is low which gets oxidised completely by the oxygen as copare to unsaturated hydrocarbons,but production of flame depends upon availability of oxygen too, in secant concentration of oxygen sooty flame or no any flame will be observed and substance at that time will produce energy slowly with sooty flame or just smoke only.

∙ 16y agobecause some liquids have chemical reactions that react to the heat to make them burn;others dont. also some different liquids need to be heated up to different temeratures in order to burn.

∙ 7y agoSome substances will rapidly combine with oxygen, and the reaction releases heat and light. That is flame.
