Determine which of the following systems is in equilibrium. a. A rigid insulated cylinder is divided by an insulated piston into two equal parts. One part contains oxygen at 50°C and 300 kPa, and the other part contains nitrogen at 30°C and 100 kPa. The piston is held in place by a stop. b. Same as part a, but the stop is removed. c. A rigid insulated cylinder is divided by a copper piston into two equal parts. One part contains oxygen at 50°C and 300 kPa, and the other part contains nitrogen at 30°C and 100 kPa. d. A rigid insulated cylinder is divided by a copper piston into two equal parts. One part contains oxygen at 30°C and 100 kPa, and the other part contains nitrogen at 50°C and 100 kPa. e. A rigid insulated cylinder is divided by a copper piston into two equal parts. One part contains oxygen at 30°C and 100 kPa, and the other part contains nitrogen at 30°C and 100 kPa. A small hole is made in the piston. f. Twenty grams of salt crystals are put in a container together with 1000 cm3 of water. g. Twenty grams of salt crystals are put in a container together with 1000 cm3 of saturated saline solution
