8. If you have a 3.0 L cylinder of compressed air that contains 2.0 g of O2, and 8.0 g of N2, then at room temperature (assume 298 K), what would be the total pressure in the tank (in atm), and the pressures of O2, and of N2 (also in atm) separately? 1. A guage on a compressed gas cylinder in a hospital reads 2.200 E3 psi (pounds per square inch). (1.00 atm = 14.7 psi). Express this pressure in...

Consider a piston-cylinder device (system) that contains 0.06 m3 of air at 300 kPa and 125 ̊C. (a) If the volume of air in the device increases to 0.15 m3 while the pressure remains constant, determine the work done by the system during the process. (b) If as a result of heat transfer to the surrounding, the pressure and temperature in the device drop to 240 kPa and 55 ̊C, respectively, and the piston is held such that the volume...

questions 4 and 5 please explain
4. A cylinder with a piston originally contains 5.0 L of He gas at a temperature of 310 K. When the gas is cooled the piston moves and the new volume is 2.4 L. What is the final temperature of the gas assuming that pressure and the number of moles of He remains constant? 5. What volume, in L, is occupied by 10.0 g N, at 30.0°C and a pressure of 385 mm Hg?
