IB Physics: Problems: Gases

1. The pressure exerted by a gas on the walls of a container is given by the equationP=1/3 ρcav2where ρ = densitycav = average speedGiven that the molar mass of air is 29g and its density is 1.3kgm-3 estimate how many molecules of air at room temperature hit 1m2 of wall per second when the pressure is 100kPa.2. The volume of a fixed mass of gas at constant pressure is inversely proportional to the pressure. A 10m3...
