An ideal monoatomic gas is taken around the cycle A B C D A as shown in the p-V diagram. The work done during the cycle is given by
Options
- A1 2 p V
- Bp V
- C2 p V
- D4 p ~V
Correct answer
B. p V
Step-by-step solution
Work done in a cyclic process is equal to the area enclosed by the cycle in p-V diagram. aligned W &= Area A B C D &=A B A D &=(2 p-p) (2 V-V)=p V=p V aligned
