C. An ideal gas undergoes the following sequences of mechanically reversible process in a close system as shown in FIGURE Q1. N PCB/ PDB 1043 3 70°C 1343.15 KN 150 C (423.15K) (343.15 K) 70 C V FIGURE Q1 Calculate the change in W, Q, U and H for each of the following three processes. Take Cv= (3/2)R, Cp = (5/2)R and R= 8.314 J/mol K İ. From an initial state of 70°C and 1 bar, it is compressed adiabatically to 150°C [3 marks) ii. It is then cool from 150°C to 70°C at constant pressure. [3 marks] iii. Finally, it is expanded isothermally to its origional state. [3 marks]
