1.	A gas can expand from 100 ml to 250 ml under a constant pressure of 2 atm. The work done by the gas is _____
Answer» SOLUTION :`DELTAV`=expansion in VOLUME =100 to 250 `DeltaV=V_2-V_1`=250-100 `DeltaV`=150 ml =0.15litre Work done = ? Pressure =2 atm `w=-P DeltaV` `=-2xx0.15 "LITRE" xx 101.3 J L^(-1) "atm"^(-1)` =-30.39 J
