Question

what happens to the molecules of gas when pressure is decreased?
a) their mean square speed decreases
b) number of Collisions between gas molecules and walls of the container decrease
c) the force of attraction decreases
d) their size increases
please tell me the answer with explanation ​

Answer 1

Answer:

b) number of collisions between gas molecules and walls of the container decrease

Answer 2

Answer:

When gas temperature increases, gas pressure increases due to increased force and frequency of molecular collisions. (b) When volume decreases, gas pressure increases due to reduced frequency of molecular collisions.
