FIDENTIAL JESTION 1 BKC/151561/BKF1253 Calculate the percentage difference in pressure of 0.01 kg of oxygen confined to a container of volume 100 cm at 25°C with assumption behave as a perfect gas and virial equation. Coefficient B--16 TX 10 mmol, C-1200 X 10 m mol (10 Marks) 5) One mole of ideal gas is at pressure P, and volume V. The gas then undergoes three processes: 1. The gas expands isothermally to 2%, while heat Q flows into the gas. 2. The gas is compressed at constant pressure back to the original volume. 3. The pressure is increased while holding the volume constant until the gas returns to its initial state. i) Draw a P-V diagram that depicts this cycle. Label relevant points on the axes In terms of Ts, the initial temperature, label each vertex with the temperature of the gas at that point. (6 Marks) ii) Determine the change in internal energy and the work done for each point of the cycle. iii) Determine the heat that flows into the gas on process 2 and 3. (6 Marks) Marks)
