chimney effect
Hot air rises
The chimney effect is the movement of air or gas through a vertical space due to temperature differences—warm air rises, drawing cooler air in below.
The principle drives natural ventilation in buildings and explains why fires draw air upward through chimneys.
In tall structures, the effect can create powerful updrafts: The stairwell's chimney effect made the fire spread rapidly.
Also called stack effect.
