A) \[{{p}_{0}}{{v}_{0}}\]
B) \[\left( \frac{13}{2} \right){{p}_{0}}{{v}_{0}}\]
C) \[\left( \frac{11}{2} \right){{p}_{0}}{{v}_{0}}\]
D) \[4{{p}_{0}}{{v}_{0}}\]
Correct Answer: B
Solution :
Heat extracted from the source \[=\frac{{{C}_{V}}}{R}({{P}_{2}}{{V}_{2}}-{{P}_{1}}{{V}_{1}})+\frac{{{C}_{P}}}{R}({{P}_{3}}{{V}_{3}}-{{P}_{2}}{{V}_{2}})\] \[=\frac{3{{P}_{0}}{{V}_{0}}}{2}+5{{P}_{0}}{{V}_{0}}=\frac{13}{2}{{P}_{0}}{{V}_{0}}\]
