Homework Statement
The figure shows a PV diagram for 2.69 mole of oxygen gas in a sealed container. The temperature of state 1 is 21 C. Pressure is Pi. What is T3 and T4?

my attempt at solving the solution:
T3 - P1V1/T1 = P3V3/T3
(1Pi)(.100l)/294K = (1.5Pi)(.05l)/T2
T2 = 220.5K - 273 = 52.5K
T4 - V3/T3 = V4/T4
(.05l)/(220.5K) = (.150l)/(T4)
T4 = 661.5K = 388.5C
