The diagram shows gas particles moving within a sealed container. These gas particles strike the container walls. The temperature of the gas is raised. What happens to the average speed of the gas particles, and what happens to the number of collisions made by the gas particles with the walls of the container?
- Aaverage speed increases; less frequent collisions
- Baverage speed increases; more frequent collisions
- Caverage speed stays the same; less frequent collisions
- Daverage speed stays the same; more frequent collisions
