18.A sample of gas is in a sealed, rigid cylinder at constant volume. Which changes occur in the force of collisions of the gas particles and frequency of their collisions when the sample is cooled?
(1) Force of collisions decreases and frequency of collisions increases.
(2) Force of collisions decreases and frequency of collisions decreases.
(3) Force of collisions increases and frequency of collisions increases.
(4) Force of collisions increases and frequency of collisions decreases.
Solution:
When the sample is cooled, force and frequency of collisions of gas particles will decrease. Choice 2 is the correct answer.
