Problem
Two rigid containers A and B are filled with ideal gases and are connected by a thin tube fitted with a stop-cock. The details are:
Container A : volume 1.80L, temperature 320K, pressure 1.20×105Pa, gas = argon.
Container B : unknown volume VB, temperature 290K, pressure 0.90×105Pa, gas = neon.
The stop-cock is opened momentarily so that a small amount of gas can pass until the number of molecules in each container becomes equal. The temperature and pressure in each container remain unchanged during the brief exchange.
(a) Show that the final condition implies VAPA/TA=VBPB/TB.
(b) Using the data given, calculate the volume VB of container B.
(c) How many moles of gas are finally present in each container?
