What is the makeup of the atmosphere?
- Approx. 21 % Ox
- 78% Ni
- 1 % argon and other mixed gases
-
three basic spheres
troposphere, stratosphere, and ionosphere
-
a. Where we fly
b. 20,000- 65,000 ft
c.The temperature decreases with altitude 4
degrees/1000 ft
troposphere
-
a.30 miles- 160,000 miles
b.the temperature
increases with altitude from about -76 degrees C to -40 degrees C
stratosphere
-
a.160,000 miles- Space
b.1st section’s temperature decreases
from -93 degrees C
c.2nd section’s temperature decreases
from extreme colds
ionsphere
-
F+460
F to Rankin conversion
-
C+273.15
Celsius to Kelvin conversion
-
Pressure/Absolute Temperature
density
-
(t/f) Warmer air can hold more water which is why
there is high humidity
true
-
(t/f) humid air is heavier
false
-
(t/f) Relative humidity increases as air density
decreases
false
-
What is the ratio between water vapor (OH) and cool air (H2O)
(OH) is (5/8) weight of H2O
-
(t/f) wet air weighs more
false, it weighs more when dry
