Hint: For a fire to exist there is a need for three things namely fuel, oxygen, and heat. If all these conditions are fulfilled then there can be the existence of fire. When all the necessary conditions are met then the temperature at which the fire just starts to form is the lowest temperature that is needed for the fuel to start burning. Any temperature below this lowest temperature will be unable for the burning process to take place. Any temperature above the lowest temperature will favor the burning process as long as the other conditions are fulfilled.

Note: 1. Fires that burn at a temperature like $400^\circ C$ are called cool flames.
2. Burning and catching fire are two different things. Paper may start burning or discoloration at the temperature of $150^\circ C$ but catches fire at nearly $230^\circ C$.
