Answer:
a) the number of particles increases
b) average distance between them should decrease
c) the number of particles decreases, the pressure must also decrease
Explanation:
a) When the girl pumps to increase the pressure inside the tire she introduces more particles. Therefore the number of particles increases
b) as the volume of the tire does not change and there are more particles, the average distance between them should decrease
c) When a hole is opened, some of the particles inside the tire come out, so as the number of particles decreases, the pressure must also decrease
