The burning of charcoal is a spontaneous process yet heat must first be applied to start a charcoal why?
Burning charcoal is spontaneous, but not at room temperature. To start the combustion energy must be added (in the form of heat). Once the temperature of the charcoal reaches a certain temperature it reacts exothermically and releases heat. This heat of reaction is sufficient to locally heat more charcoal so that it burns continuously.
