An ideal-gas undergoes the following sequence of mechanically reversible processes in a closed system: (a) From an initial state of 50 and 1 bar, it is compressed adiabatically to 170 . (b) Then it is cooled to 50 at constant pressure. (c) Finally, it expands isothermically to its original state. Calculate W, Q, ∆U and ∆H for each of the three processes and for the entire cycle. cP = 20.785 J mol−1K−1 and cV = 12.471 J mol−1K−1.
