Answer -
Three things are needed to make fire-fuel, oxygen and heat. First as three things are needed to start a fire, there are three main ways in which a fire can be put out. In each, one of the three things needed for burning is taken away. For example, we can take away the fuel. If the fire has no fuel to feed on, no burning can take place. The second way of putting out a fire is to prevent oxygen from reaching it. No supply of oxygen means no fire. The third way is to remove the heat. If the temperature can be brought down below the flash point, the fuel stops burning.
