In order for something to burn there must be heat. If new fuel in not heated than a fire cannot spread. The effects of fire come from the movement of heat away from the flame and into an area where there in no new fuel. If the heat is taken away the fire goes out.

There are three ways heat can move. Conduction is the transfer of heat through a solid like the heat we can feel when we touch the outside of a hot stove. Convection is the transfer of heat like the heat that goes from hot water to peas when we boil them. Radiation is the transfer of heat we can feel without touching it like the heat from the sun or from a heater.

When there is a fire in a room it moves heat in all three ways. The fire conducts heat through the wall to another room. Heat moves from the fire to the smoke through convection. The hot smoke radiates heat down to the floor and everything else in the room.
