ANSWERS.VERIFED/GRADED
What is the composition of the atmosphere? - (ANSWER)78% nitrogen, 21%
oxygen, 1% other.
Earth's atmosphere is considered a: - (ANSWER)Fluid.
Atmospheric pressure is the: - (ANSWER)Weight of the surrounding air.
Atmospheric pressure is heaviest at: - (ANSWER)Sea level.
What instrument is used to measure atmospheric pressure? -
(ANSWER)Barometer.
What units do barometers use? - (ANSWER)Inches of mercury (In. Hg.).
What units do aviation altimeters use? - (ANSWER)In. Hg.
Atmospheric pressure ( ) as altitude increases. - (ANSWER)Decreases.
Conditions of a standard day. - (ANSWER)14.7 psi, 29.92 In. Hg., 15 degrees
Celsius or 59 degrees Fahrenheit, gravity 9.81 m/s^2 or 32.174 ft/s^2.
, 2
The approximate rate atmospheric pressure drops as an aircraft ascends. -
(ANSWER)1 In. Hg. per 1000 ft
The approximate rate temperature drops as an aircraft ascends. - (ANSWER)2
degrees Celsius or 3.5 degrees Fahrenheit per 1000 feet.
Air is subject to which state of matter's laws? - (ANSWER)Gas laws.
As density increases, pressure: - (ANSWER)Increases.
Density varies ( ) with temperature. - (ANSWER)Inversely.
Is cool air more dense or less dense than hot air? - (ANSWER)More dense.
An aircraft can fly faster at a higher altitude due to: - (ANSWER)Lower air density
(creates less resistance on surfaces of aircraft).
Humidity is defined as: - (ANSWER)The amount of water vapor displacing the air.
The maximum amount of water vapor that air can hold varies with: -
(ANSWER)Temperature.
, 3
If air temperature increases, does the amount of water vapor in the air decrease?
- (ANSWER)No, it will increase.
Do humidity and air density vary inversely with one another? - (ANSWER)Yes, as
one increases the other decreases.
Why do humidity and air density vary inversely with one another? - (ANSWER)As
humidity increases, more water vapor is present in the air and displaces air
particles, leading to lower air density.
What is the main difference between speed and velocity? - (ANSWER)Speed is an
object's rate of motion in relation to time, velocity is an object's rate of motion in
relation to time in a specific direction.
What is acceleration? - (ANSWER)The rate at which velocity changes.
Newton's first law of motion: - (ANSWER)An object will remain at rest or in
uniform motion in a straight line unless acted upon by an external force.
Newton's second law of motion: - (ANSWER)The acceleration of an object
depends on the mass of the object and the amount of force applied (mass times
acceleration is equal to net force).
Newton's third law of motion: - (ANSWER)For every action there is an equal and
opposite reaction.
