A camping gas canister contains liquefied fuel at the bottom, with gas particles in the space above that are constantly moving.
Explain, in terms of particles, how the gas produces a pressure on the inside walls of the canister.
As the canister is used to run a portable stove, liquid fuel leaves the canister. A student concludes:
"I think that the pressure of the gas inside the canister decreases as the liquid fuel is consumed."
Evaluate this student's conclusion.
What happens to the average speed of the gas particles if the canister is cooled by placing it in cold water?
