The volume of air increases and the air becomes less dense because the volume is inversely proportional to density. Hence, a lesser volume of oxygen is available for breathing. Thus, mountaineers have to carry oxygen cylinders with them. 📌Mountaineers carry oxygen cylinders with them because in high altitudes atmospheric pressure is low which makes air less dense. This makes the volume of Oxygen for breathing very less. #Information ##intermediate 📒@English_4U📒
