How much does air weigh? |
||||||||
| It might not seem like it, but air has weight. In fact, anything that has mass, also has weight. The fact that you can feel the wind blow against you means air has mass. At sea level, the total weight of the atmosphere exerts a pressure of about 14.7 pounds per square inch. You don't notice this weight, however, because you are used to it. If you live in Denver, Colorado, which is at an elevation of about 5,000 feet, then about 15% of the mass of the atmosphere is below you, resulting in an air pressure of about 12.5 pounds per square inch. At the top of Mount Everest (over 29,000 feet), 70% of the atmosphere lies below, leaving an air pressure of only 4.4 pounds per square inch. | ||||||||
