Use image below Part A - Evaluate the volume and internal energy of the air in the initial state 1, in the intermediate state 2, and in the final dead state DS. Also evaluate the temperature of the air in the intermediate state 2. PArt B - Plot the processes 1 → 2 → DS on P–v, T–v, P–s, and T–s diagrams. Mark states 1, 2, and DS on the graphs, and make sure that it is clear when a given quantity increases, decreases, or remains constant.

Question
Use image below Part A - Evaluate the volume and internal energy of the air in the initial state 1, in the intermediate state 2, and in the final dead state DS. Also evaluate the temperature of the air in the intermediate state 2. PArt B - Plot the processes 1 → 2 → DS on P–v, T–v, P–s, and T–s diagrams. Mark states 1, 2, and DS on the graphs, and make sure that it is clear when a given quantity increases, decreases, or remains constant.
Consider a piston-cylinder device containing \( m = 1 \, \text{kg} \) of air at the initial temperature \( T_1 = 900 \, \text{K} \) and pressure \( P_1 = 895 \, \text{kPa} \) (state 1). The ambient temperature and pressure are maintained at \( T^{(e)} = 300 \, \text{K} \) and \( P^{(e)} = 100 \, \text{kPa} \). The air expands in a reversible adiabatic process until the air pressure reaches the ambient pressure \( P^{(e)} \) (the intermediate state 2). Subsequently, the system undergoes an isobaric process until it reaches the dead state DS.
