The particles of a gas in a sealed container are constantly moving and colliding with the container walls, exerting a pressure.
Which row in the table correctly describes the relationship between a change in the gas pressure and the rate of particle collisions with the walls of the container?
| Change in gas pressure | Rate of particle collisions with the container walls | |
|---|---|---|
| A | Decreases | Decreases |
| B | Decreases | Increases |
| C | Increases | Decreases |
| D | Increases | Stays the same |
