An inflated car tyre is considered to have a constant volume regardless of any changes in temperature or pressure. Use the Kinetic theory of gases to answer the following questions:
a) How does the air in tyre exert a pressure on the walls of the tyre?
b) Why is the pressure the same at all points on the inside walls of the tyre?
c) What happens to the pressure on the inside walls of the tyre if the temperature of the air increases? Explain your answer.
d) What happen when more air is pumped into the tyre while the temperature is kept constant?
