1.	A gas expands in a piston cylinder device from volume V_1 to V_2,the process being p = a/V + b where p = pressure, V = volume. The work done in the process is
Answer» `-a LN (V_1/V_2) + B(V_2 -V_1)` `-a ln (V_2/V_1) -b (V_2-V_1)` `-a ln (V_1/V_2) - b (V_2 - V_1)` `a ln (V_1/V_2) + b(V_2-V_1)` ANSWER :A
