A gas in a rigid container is heated, so its temperature increases, but the volume of the container remains constant. Which row in the table correctly describes the changes in the pressure of the gas and the average kinetic energy of its particles?
| Pressure of gas | Average kinetic energy of gas particles | |
|---|---|---|
| A | decreases | decreases |
| B | decreases | increases |
| C | increases | decreases |
| D | increases | increases |
