Question

The air temperature in the atmosphere decreases at the rate of 7 degrees Celsius every 250 meters. What height would be a plane have to fly to expeience a temperature of - 49 degrees celsius?

Answer 1

Answer:

Air is all around us, but we cannot see it. Gravity from the Earth pulls air down - this is called air pressure. We don't feel this pressure because our bodies push an equal amount of pressure outward. This graph shows how air density and air pressure changes with altitude (the distance above sea level). Barometers are used to measure air pressure in milibars.
