A) \[-20\,J\]
B) \[100\,J\]
C) \[150\,J\]
D) \[50\,J\]
Correct Answer: C
Solution :
For a cyclic process, Net heat supplied = net work done \[{{Q}_{1}}+{{Q}_{2}}+{{Q}_{3}}+{{Q}_{4}}+{{W}_{1}}+{{W}_{2}}+{{W}_{3}}+{{W}_{4}}\] Substituting the respective values, we get \[600-400-300+200=300-200-150+{{W}_{4}}\] or \[100=-50+{{W}_{4}}\,\,\,\,\Rightarrow \,\,\,\,{{W}_{4}}=150\,\,J\]You need to login to perform this action.
