A canister of compressed nitrogen gas is used to quickly inflate bicycle tires.
Explain how the nitrogen gas causes a pressure on the inside walls of the canister. Refer to particles in your answer.
Explain what happens to the pressure of the nitrogen gas inside the canister as its temperature increases.
A fixed mass of nitrogen has a volume of 28 000 cm328\,000\text{ cm}^328000 cm3 when its pressure is 100 kPa100\text{ kPa}100 kPa.
Calculate the pressure of this fixed mass of nitrogen when it is compressed inside the canister.
[volume of nitrogen in canister = 4000 cm34000\text{ cm}^34000 cm3]
