Question

Detectors in the walls of four containers (A–D) count the number of collisions between gas molecules and the surfaces of the containers. The detectors count 10, 15, 20, and 30 collisions per second for containers A, B, C, and D, respectively.

Which container has the lowest pressure?
A
B
C
D

Answer 1

the answer is A

Answer 2

I think it should be A because it has the least number of collisions hence the least pressure
