2 2 A Estimate As Accurately As You Can From Fig 2 1 The Molal Specific Volume Of Co At A Pressure Of 3 X 10 Nm And 2 (71.39 KiB) Viewed 37 times

2-2 (a) Estimate as accurately as you can from Fig. 2-1 the molal specific volume of CO, at a pressure of 3 x 10'Nm- and a temperature Tn. Assume T, = 340 K. (b) At this pressure and temperature, how many kilomoles of Co, are contained in a tank of volume 0.5 mº? (c) How many kilomoles would the tank contain if CO, were an ideal gas ? 2-3 A cylinder provided with a movable piston contains an ideal gas at a pressure P specific volume vu, and temperature Ty. The pressure and volume are simultaneously increased so that at every instant P and v are related by the equation P = Av, where A is a constant. (a) Express the constant A in terms of the pressure P, the tempera- ture Ty, and the gas constant R. (b) Construct the graph representing the process above in the P-, plane. (c) Find the temperature when the specific volume has doubled, if T, = 200 K.
106 R = 8.3143 x 10! Ideal gas T; T: Pu/T (J kilomole 'K') T; > T2 >T, T: 6 8 x 10 Pressure (Nm) Fig. 2-1 The limiting value of Pu/T is independent of T for all gases. For an ideal gas, Pv/T is constant.
