Question 15

An airtight container is fitted with a frictionless, movable piston that maintains a constant pressure of the gas inside. The container is heated, causing the temperature of the gas to increase.

Which of the following correctly describes what happens to the gas inside the container?

A

Average distance between gas particles: increases; average speed of gas particles: no change

B

Average distance between gas particles: increases; average speed of gas particles: increases

C

Average distance between gas particles: no change; average speed of gas particles: increases

D

Average distance between gas particles: decreases; average speed of gas particles: increases
