A tire holds air (assume it's all N2) at a pressure of 3 atm, andin one week the pressue drops by 1% because of inevitable leakageat the rim, when the temperature is 300 K. Calculate the area ofthe hole. [Hint: because the pressure change is small, you canassume the pressure to be 3 atm, even thought it DOES drop slightlyover time] How many molecules have escaped the tire during theweek
I'm stuck because I don't have a number of moles of nitrogen gas ora volume. I know N (number of molecules)= PV/ KbT. the time it tookfor it to decrease by 1% is 6.048 x 10^5 sec...
