1.	In the `P-V` diagram shown in figure `ABC` is a semicircle. The work done in the process `ABC` is A. zeroB. `(pi)/(2) atm-It`C. `-(pi)/(2) atm-It`D. `4 atm-It`
Answer» Correct Answer - B `W_(AB)` is negative (volume is decreasing ) and `W_(BC)` is positive (volume is increasing ) and since ,`\|W_(BC)\|gt\|W_(AB)\|` `:.` Net work done is positive and area between semicircle which is equal to `(pi)/(2)` atm-it.
