Indicate the effect on the pressure of the following change.
-Some molecules of gas are removed (V, T constant).

Question

Quizplus · Accepted Answer

When some molecules of gas are removed from a container while keeping temperature and volume constant, the number of collisions between the gas molecules and the walls of the container decreases. This results in a decrease in the pressure of the gas. Therefore, the best choice is B, which indicates a decrease in pressure.
