How cold is it at 15000 ft?

How cold is it at 15000 ft? After that altitude (in the stratosphere), temperatures begin to slowly rise until the mesosphere is reached (165,000 feet or 50,000 meters) Example: If the temperature is 76 degrees at ground level, it will be 58 degrees at 5,000 feet, 40 degrees at 10,000 feet and 22 degrees at 15,000 feet, 4 degrees at 20,000 feet, ...

Why is it so cold at 35000 feet?

Air itself is constantly in motion; it will often rise toward the sky. But, any air that rises will expand and cool, as it encounters progressively lower atmospheric pressure (explained further in the next section). The upshot is that the air outside a plane will be much colder than at ground level.

Is there oxygen at 35000 feet?

Planes have lower oxygen levels If this didn't happen, everyone inside the plane would die, as the low air pressure at the elevations planes fly (typically 35,000 feet or so) means there isn't enough oxygen present for your body to function.

How high can humans go in the air?

Above about 8,000 meters (26,000 feet), the human body cannot survive at all, and starts to shut down. Mountaineers call this altitude the death zone. To prevent severe altitude sickness, mountaineers bring supplemental (extra) supplies of oxygen and limit their time in the death zone.

How fast would you freeze in space?

Your body would take between 18-36 hours to freeze in space due to the radiational cooling. There are other problems when it comes to being stranded in space though. While freezing is not your most immediate concern, oxygen and extreme low pressure are things to be concerned about.

Can a human survive at 35000 feet?

Airlines these days cruise at around 35,000 feet, some higher and some lower, but without protection at these altitudes a human being cannot survive.

At what altitude do you need oxygen?

For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.

Why do planes fly at 37000 feet?

The reason commercial airplanes fly at 30,000 to 36,000 feet is because it places them in a unique part of Earth's atmosphere known as the lower stratosphere. The lower stratosphere is above the clouds, so commercial airplanes are protected against bad weather.
