Exercise: 
Cyclic Process - Adiabatic, Isobaric, Isothermal steps
An ideal gas undergoes the following reversible processes:
(a) From an initial state of 343 K and 1 bar it is compressed adiabatically to 423 K.
(b) It is then cooled to 343 K at constant pressure.
(c) Finally, it is expanded to its original state isothermally. Calculate \( \Delta \)U, \( \Delta \)H, W and Q for each step as well as for the entire cycle. Assume CV = (3/2)R.
