Summary

Density contrast produces buoyancy in hot fire gases. Based on Kandola (2002), pp. 1-4–1-5 and Van Rossum (2027), §3.2.

Diagram for the article Buoyancy (Fire Safety Academy wiki, level 1 Basic).

Short title	Less dense hot gas rising through denser cool gas under pressure differences.
Image title	A region of hot, less dense gas (about 0.75 kg/m³ at 200 °C) surrounded by cool, denser gas (about 1.2 kg/m³ at 20 °C). Pressure arrows on the lower boundary are longer than those on the upper boundary. A force diagram shows the upward buoyant force larger than the downward weight, drawn to the density ratio 1.2 : 0.75.
