**drwls**, Thursday, May 6, 2010 at 1:04amAt constant T, Volume V is inversely proportional to P. Therefore

PV = P1*V1

Compute V1 first of all

V1 = nRT/P1 = 134 liters = 0.134 m^3

P1 = 1 atm = 1.013*10^5 N/m^2

Work done on gas =

-Integral of P dV = -P1*V1 Integral of dV/V

= P1*V1 ln (V1/V2) = P1*V1*ln(P2/P1)

= P1*V1 ln3 = 1.49*10^4 Joules
