Determine from the following data the type of process path going from state 1 to state 2, give your reason: (a) R = 1 bar, y = 0.5 m, R = 2 bar, k = 0.25 m3, Q+ 0 and WE 0. (2 marks) (b) R = 1 bar, y = 0.5 m, R = 2.64 bar, k = 0.25 m2, Q = 0 and W = -39.938 kJ. (2 marks) (C) R = 1 bar, k = 0.5 m, R = 2.30 bar, k = 0.25 m, Q+ 0 and W = +37.175 kJ. (2 marks)
