1.	An ideal gas of volume 1 litre and at a pressure 8 atm undergoes an adiabatic expansion until its pressure drops to 1 atm and volume increase to 4 liters. Calculate the work done in the process (y = 1.5).
Answer» Solution :`W = ( 1hgamma -1) (P _(1) V _(1) - P _(2) V _(2))= (1//15 -1) (8 XX 1.103 xx 10 ^(5) xx 10 ^(-3) - 1. 013 xx 10 ^(5) xx 4 xx 10 ^(-3)) = 810 J `
