After a long journey, the pressure of the air in a car tyre increases. This happens because the average speed of the air particles changes and the temperature of the air in the tyre changes. Which row shows the changes that have led to the rise in air pressure in the tyre?
- Aaverage speed of the air particles decreases; temperature of the air decreases
- Baverage speed of the air particles decreases; temperature of the air increases
- Caverage speed of the air particles increases; temperature of the air decreases
- Daverage speed of the air particles increases; temperature of the air increases
