Question

Which of the following describes air temperature and air pressure at higher altitudes? (2 points)

a
Air temperature increase while air pressure decreases

b
Air temperature and air pressure both decrease

c
Air temperature and air pressure both increase

d
Air temperature decreases while air pressure increases

Answer 1

Answer:

(a) As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases. Air density will decrease by about 1% for a decrease of 10 hPa in pressure or 3 °C increase in temperature

(d) Cool Temperatures

Decreased velocity results in fewer collisions between molecules and air pressure decreases. Air density plays a role in the correlation between temperature and pressure because warmer air is less dense than cool air, allowing molecules to have more space to collide with greater force.
