Chimney Effect Fact #shorts

Why is it that when a skyscraper is engulfed in flames, the fire spreads very quickly to the end of the building in just a few minutes? Actually, this happens because of the chimney effect. The principle occurs when the combustion of an object that heats the surrounding air, it will produce hot air which then rises with the smoke, creating a vacuum at the base of the smoke column. This vacuum effect draws cold air through the entrance, causing the fire to get worse.
