Natural gas burns hotter than oil. Natural gas has a higher heating value per unit volume compared to oil, making it a more efficient and hotter-burning fuel.
The smoke rises due to a particular cause.The candle burns due to the vaporization of the oil contained in the candle.Now,when the vapor burns it releases some gases like carbon di oxide etc.This is why they release smoke.
