Atmospheric pressure decreases with an increase in altitude because:
A
Acceleration due to gravity increases with altitude.
B
Temperature increases with altitude.
C
Internal energy increases with altitude.
D
Interaction among air molecules decreases due to less quantity of air.
Verified Correct Answer: D.
Physical Principles & Numerical Solution
As altitude rises, there is less air above a particular point, leading to a decrease in atmospheric pressure. Furthermore, the density of air diminishes with increased altitude, which also contributes to this phenomenon.
