V1 = 1.3
V2 = 6.3
T1= T2
a) When P = 0
W = -P*(Vf-Vi) = 0 since there is no pressure (force) to do work against
b) If P = 0.62 atm 62821.5 Pa
W = -P(Vf-Vi) = -62821.5*(6.3-1.3)*10^-3 = -314.11 J = - 3.14*10^2 J
c)If P = 4.5 atm 454962.5 Pa
W = -P(Vf-Vi) = -454962.5*(6.3-1.3)*10^-3 = -2274.81 J = -2.27*10^3 J
