The Figure Shows a PV Diagram for 4

Question 28

Multiple Choice

The figure shows a pV diagram for 4.3 g of oxygen gas (O2) in a sealed container. The temperature T1 of the gas in state 1 is 21°C. What are the temperatures T3 and T4 of the gas in states 3 and 4? The ideal gas constant is R = 8.314 J/mol ∙ K = 0.0821 L ∙ atm/mol ∙ K, and the ATOMIC weight of oxygen is 16 g/mol.
