Here are the solutions to the questions based on the provided pressure-volume diagram: Given Data: Adiabatic index, = 1.4 Mass of gas, m = 1 kg Specific entropy at point 1, s_1 = 0.515 kJ/kg.K State Points from Diagram: Point 1: P_1 = 100 kPa, V_1 = 0.082 m^3 Point 2: V_2 = 0.0054 m^3 Point 3: P_3 = 6200 kPa, V_3 = 0.0054 m^3 Point 4: P_4 = 6200 kPa, V_4 = 0.0125 m^3 Point 5: V_5 = 0.082 m^3 --- 1.1 The work done during adiabatic compression The adiabatic compression process is from point 1 to point 2. Step 1: Calculate the pressure at point 2 (P_2) using the adiabatic relation P_1V_1^ = P_2V_2^. P_2 = P_1 ((V_1)/(V_2))^ P_2 = 100 kPa × (0.082 m^30.0054 m^3)^1.4 P_2 = 100 kPa × (15.185)^1.4 P_2 = 100 kPa × 36.790 P_2 = 3679.0 kPa Step 2: Calculate the work done during the adiabatic process 1-2. For an adiabatic process, the work done by the system is given by: W_1-2 = (P_1V_1 - P_2V_2)/( - 1) W_1-2 = (10
