[Mohankpvk]

Is there any difference between setting petrol on fire directly(by contacting it with burning stick) and heating petrol in a vessel, increasing its temperature above itself ignition temperature and making it burn spontaneously?
What is the difference between flash point,fire point and self ignition temperatures?
