One-quarter Ibmol of oxygen gas (O₂) undergoes a process from p₁ = 20 lbf/in², T₁ = 500°R to p₂ = 150 lb/in². For the process W =
-500 Btu and Q = -202.5 Btu. Assume the oxygen behaves as an ideal gas.
Determine T2, in °R, and the change in entropy, in Btu/°R.
Carbon dioxide (CO₂) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 30 lb-/in², and a volume of 1.8 ft³. The gas is
stirred until its temperature is 500°F. During this process heat transfer from the gas to its surroundings occurs in an amount 2.6 Btu.
Assume ideal gas behavior, but do not assume constant specific heats. Kinetic and potential energy effects can be ignored.
Determine the mass of the carbon dioxide, in lb, and the work, in Btu.
One kg of an ideal gas (gas constant R = 287 J/kg.K) undergoes an irreversible process from state-1 (1
bar, 300 K) to state -2 (2 bar, 300 K). The change in specific entropy (52 - s1) of the gas (in J/kg. K) in
