How do you find the temperature with altitude?
For example, in the troposphere, the variation of temperature with altitude is given by the equation T = T0 – λ h (2.4) where T0 is the sea level temperature, T is the temperature at the altitude h and λ is the temperature lapse rate in the troposphere.
How do you find the temperature of a place?
- Place the thermometer 5 feet above the ground (+/- 1 ft.). ...
- The thermometer must be placed in the shade. ...
- Have good air flow for your thermometer. ...
- Place the thermometer over a grassy or dirt surface. ...
- Keep the thermometer covered.
What is the temperature at 23000 ft?
Near the equator, the lower edge of the stratosphere is as high as 20 km (66,000 ft; 12 mi), at midlatitudes around 10 km (33,000 ft; 6.2 mi), and at the poles about 7 km (23,000 ft; 4.3 mi) Temperatures range from an average of −51 °C (−60 °F; 220 K) near the tropopause to an average of −15 °C (5.0 °F; 260 K) near the ...
How cold is it at 1000 feet?
The temperature at the base/village should be around 46°F (3,000 ft. elevation change at 5.4°F per 1,000 feet equals about a 16°F temperature increase).
Is it true that temperature increases as altitude increases?
As you increase in elevation, there is less air above you thus the pressure decreases . As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
What is the standard temperature at 20000 ft?
up to 20,000 meters (approximately 65,600 ft.), constant temperature is -56.5°C (-69.7°F) , and this is also the lowest assumed temperature in respect to ISA.
What is ISA temperature at 12000 feet?
| Altitude (feet) Abs. Pressure (in. Hg) Temp. (F) | 10000 20.57 23.3 | 12000 19.02 16.2 | 14000 17.57 9.1 | 16000 16.21 1.9 |

How cold is it at 40000 feet?
After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit .
Can a smartphone be used as a thermometer?
With the right app, your Android smartphone or tablet can function as a thermometer using your device's built-in temperature sensor . However, even if your mobile device is not equipped with a temperature sensor, there is still a way to get a decent temperature reading for the surrounding air.
Can my phone tell the temperature?
While your smartphone has temperature sensors, they do not measure the temperature of the room . Instead, these sensors perform a vital function for your phone, preventing damage to your battery and other components from overheating.
What are the 3 ways to measure temperature?
There are three different systems for measuring heat energy (temperature): Fahrenheit, Celsius, and Kelvin . In scientific measures, it is most common to use either the Kelvin or Celsius scale as a unit of temperature measurement.
How cold is it at 35000 feet?
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.
Can you breathe at 35000 feet?
Partial pressures. You can breath at 35,000 ft without a pressured suit, but go much higher and you can't . At sea level, you have 760 mmHg of air pressure. ... At 35,000 ft, air pressure is 179 mmHg [1], so if you breath 100% pure oxygen, you're getting the same amount of oxygen you'd get at sea level.
Why do planes fly at 35000 feet?
A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.
