How do fire typically spread?
The heat from the fire can heat the air, to a very hot temperature. Hot air will always rise and it will flow under the ceiling of a room spreading the heat from the fire. This is the main way in which a fire spreads throughout a house. When a fire is burning large amounts of hot gases and smoke are produced.
