A gas in a sealed, rigid container is heated so that its temperature increases. The volume of the gas does not change.
Which row in the table correctly describes the resulting changes in the pressure of the gas and the average kinetic energy of the gas particles?
| Pressure of gas | Average kinetic energy of particles | |
|---|---|---|
| A | increases | increases |
| B | increases | decreases |
| C | decreases | increases |
| D | decreases | decreases |
