The atmosphere are divided in the Troposphere - ranging 0 to 11 km (36.000 ft) altitude the Stratosphere - ranging 11 to to 51 km (167.000 ft) altitude This is equivalent to a yearly combustion of 100 grammes of carbon and hydrocarbons on each square meter (approximately 3 ounces per square yard) of the surface of the mass. Next Level 3600 T-shirts, Calumet and Hecla on peninsula in lake I especially love to nerd out about choosing the right luggage. Weight in grams = volume density. Long answer I will tell you a way to calculate the temperature at any altitude and airplane speed by your own. According to USA Today, a Boeing 767 has a service ceiling of 43,000 feet. 59.0 To determine the speed of sound in air, follow these steps: The speed of sound increases as the air temperature increases. The average temperature in a commercial aircraft is between 50 and 60 Fahrenheit, well above the freezing point. Discover world-changing science. What is the temperature change per meter of altitude from 500 meters to 1,000 meters of altitude? 73 Air is almost an ideal gas. Even at a cruising altitude of 35,000 feet, you shouldn't have trouble breathing. Thanks for reading Scientific American. At 35,000 ft. (11,000 m), the typical altitude of a commercial jet, the air pressure drops to less than a quarter of its value at sea level, and the outside temperature drops below negative 60 degrees Fahrenheit (negative 51 degrees Celsius), according to The Engineering Toolbox.
