8. Consider the indicator diagram below for a monatomic ideal gas. The cycle is defined to progress along the paths AB;BC;CD;DA. The following values are given: PC= PD=1.50atm;VC=20.0dm3;VD=30.0dm3; and VB=5.10dm3. Do not assume anything else about the diagram. (a) Clearly label what processes are occuring along each path. Use thermodynamic terminology. (b) Calculate the moles of gas present. (c) Calculate any missing temperatures, pressures, and volumes. (d) For each path, calculate w,q,U, and H
