Avessel, divided into two parts by a partition, contains 4 mol of nitrogen gas at 75oc and 30 bar on one side and 2.5 mol of argon gas at 130oc and 20 bar on the other. if the partition is removed and the gases mix adiabatically and completely, what is the change in entropy? assume nitrogen to be an ideal gas with cv=2.5r, and argon to be an ideal gas with cv=1.5r.
