1.	`P - V` diagram of an ideal gas is as shown in figure. Work done by the gas in process `ABCD` is A. `4 P_(0) V_(0)`B. `2 P_(0) V_(0)`C. `3 P_(0) V_(0)`D. `P_(0) V_(0)`
Answer» Correct Answer - C c. `W_(AB) = - P_(0) V_(0)` `W_(BC) = 0` and `W_(CD) = 4 P_(0) V_(0)` `W_(ABCD) = - P_(0) V_(0) + 0 + 4 P_(0) V_(0)` `= 3 P_(0) V_(0)`
