Given that the gases rise and grow, they also begin to communicate with air flow openings. The motion of smoke from a compartment into an adjoining House is controlled from the density differences with the interface in the air flow opening. Higher layer gases In the compartment are pushed by density variations due to their higher temperature and reduce density. These gases are buoyant as compared to the encompassing air at the opening interface, which leads to them to movement in the opening, Unless of course there is wind or Various other exterior power (mechanical air flow) letting the pressure outside of the compartment to get better.
