Question 7

A pressure sensor is taken from a coastal weather station to a station on a hill. Its reading is lower at the hill. Which statement explains this difference?

[1]
A

The air molecules at the hill are more spread out, so more of them collide with the sensor

B

The air is less dense at the hill, so fewer air molecules collide with the sensor

C

The air is denser at the hill, so its molecules collide less often with the sensor

D

There is more air above the sensor at the hill, so its molecules cause fewer collisions
