A car tyre has a fixed mass of air temperature of 30ᴼC. The air pressure was 320 kPa above the atmospheric pressure. After a high speed chase, the air pressure in the tyre was 370kPa above atmospheric pressure.(i) Apply the kinetic theory of matter to explain the increased pressure in that tyre. ​

Final answer:

Increase in pressure of a car tire after a high-speed chase can be explained by the kinetic theory of matter, which relates temperature and pressure due to more frequent and forceful collisions of gas molecules against the tire walls when temperature rises.

Step-by-step explanation:

The increased pressure in the car tire after a high speed chase can be explained using the kinetic theory of matter. According to this theory, molecules of a gas move randomly and collide with the walls of their container, which in this case, is the tire. When the temperature of a gas increases, the kinetic energy of the molecules also increases, leading to more frequent and forceful collisions with the tire walls. This results in an increase in pressure within the tire. In the given scenario, the rise in pressure from 320 kPa to 370 kPa above atmospheric pressure is attributed to the increase in temperature due to the high speed chase, given that the tire's volume and the amount of gas remain constant.
