The volume of a container containing a gas is increased by 50%. Which of the following quantities decreases?

Question

Quizplus · Accepted Answer

When the volume of a container is increased, the density of the gas decreases because the same number of particles is spread over a larger volume. This results in a decrease in the number of collisions of gas particles with the walls of the container per unit time, thereby reducing the force exerted by the gas per unit area of the container (pressure). The average velocity, root mean squared speed, and average speed of the gas particles do not change with volume if the temperature is constant. The number of gas particles within the container also remains the same.
