Question

What is the difference between the burning of a candle and the burning of a fuel like coal

Answer 1

burning of a candle is different from burning of a fuel like coal because when a candle burns it burns with the help of it's oxygen and it's ignition temperature,due to this the candle burns freely. but when it comes to fuel it burns with the help of oxegen and it's evaporation in heat because heat evaporates soon in the atmosphere to catch fire easily.the difference in these two is 1: oxegen takes place in both conditions. 2: whereas in the second part the condition takes place with it's ignition temperature in the burning candle and evaporation in heat takes place in burning of fuel like coal.
