A) 5 kJ
B) 25 kJ
C) 15 kJ
D) 20 kJ
Correct Answer: C
Solution :
Process \[l\to 2\] and Process\[3\to 4\] are isochoric processes. \[{{W}_{12}}=0,{{W}_{34}}=0,{{W}_{23}}=nR({{T}_{3}}-{{T}_{2}})\] \[=3R(1600-400)\] \[{{W}_{41}}=nR({{T}_{1}}-{{T}_{4}})=3R(200-800)=-1800R\] \[W=(3600-1800)R=1800R=15kJ\]You need to login to perform this action.
