Problem 3 A well-insulated gas container with a volume of 0.1m3 is partitioned by a membrane into two equal parts. One part of the container is filled with 2 moles of argon at 300K. (a) The other part of the container is vacuum. If the membrane is removed and the gas fills the whole container, what would be the final temperature? (a) The other part is filled with 3 moles of nitrogen at 320K. If the membrane is removed and the gases mix and fill the whole container, what would be the final temperature? [30 marks] Data: CV,Ar=(3/2)R,CV,N2=(5/2)R, and R=8.314Jmol1K1
