A Well insulated piston-cylinder assembly is connected to an air supply line at 8 bar, as shown in the figure. Initially, the air inside the cylinder is at 1 bar, 300K, and the piston is located 0.5 m above the bottom of the cylinder. The atmospheric pressure is 1 bar, and the diameter of the piston face is 0.3 m. The valve is opened and air is admitted slowly until the volume of air inside the piston has doubled. The weight of the piston and friction between the piston and cylinder wall can be ignored. Using the ideal gas model, plot the final temperature, in Kelvin, and the final mass, in kilograms, of the air inside the cylinder for supply temperatures ranging from 300 to 500 K. Show your work for supply temperature of 300 K.
