An ideal gas described by the Ti=300K,Pi=1.00bar and Vi=10.0L is heated at a constant volume until P=10.0bar. It then undergoes are visible isothermal expansion until P=1.00bar. It is then restored to its original state by the extraction of heat at constant pressure. Describe this closed-cycle process in a P-V diagram. Determine w for each step and for the total process. Explain what values for w would you calculate if the cycle were traversed in the opposite direction?
