Two-tenths of a pound of air at 2 atm and 540 degrees R is trapped within a syringe by a plunger at one end and a stopcock at the other, a shown in Fig. P4.103. The stopcock is opened and the plunger moved to inject the trapped air into a container that initially holds 1 lb of air at 1.0 atm and 540 degrees R. The plunger maintains the state of the injected air constant until all has passed the stopcock. Ignoring heat transfer with the surroundings, and kinetic and potential energy effects, determine the final equilibrium temperature, in degrees R, and the pressure, in lbf/in^2, in the container following injection of the air.
