Using Energy Concepts and the Ideal Gas Model

As shown in Fig. P3.129, one side of a rigid, insulated container initially holds 2 m³ of air at 27°C, 0.3 MPa. The air is separated by a thin membrane from an evacuated volume of 3 m³. Owing to the pressure of the air, the membrane stretches and eventually bursts, allowing the air to occupy the full volume. Assuming the ideal gas model for the air, determine (a) the mass of the air, in kg, (b) the final temperature of the air, in K, and (c) the final pressure of the air, in MPa.
