Why do Firemen crawl in smoke filled rooms ?
We are unable to breathe properly when we do not crawl in smoke-filled rooms.
This is because of Density. A substance which is more denser in the air than objects on the ground is known as Density. In this case, the smoke in the air is more denser than us humans . So, if we crawl in smoke- filled rooms. We can absorb the sufficient amount of oxygen from the air. Thus, making it easy for us to breathe in smoke-filled rooms
