Extracted text: One-quarter Ibmol of oxygen gas (O2) undergoes a process from p1 = 20 Ib/in?, T1 = 500°R to p2 = 150 lb;/in?. For the process W = -500 Btu and Q = -127.5 Btu. Assume the oxygen behaves as an ideal gas. Determine T2, in °R, and the change in entropy, in Btu/°R. Step 1 Determine T2, in °R. T2 = °R Save for Later Attempts: 0 of 1 used Submit Answer Step 2 The parts of this question must be completed in order. This part will be available when you complete the part above.
