A gas is kept in a sealed container. The gas starts at a pressure of one atmosphere and a temperature of $50\,^\circ\text{C}$. It is then heated to $100\,^\circ\text{C}$. Which row gives the reason for the gas pressure and the result of raising the gas temperature?
- Acollisions between gas particles; collisions become less frequent
- Bcollisions between gas particles; the average speed of the gas particles increases
- Ccollisions between gas particles and the container; collisions become less frequent
- Dcollisions between gas particles and the container; the average speed of the gas particles increases
