Unformatted text preview: Entropy change of an ideal gas 1 mol of O 2 gas goes from T = 320 K and p = 1.6 bar to T = 410 K and p = 3.4 bar. What is the change in entropy and internal energy? How would this change for a real gas? 5 blank 6 blank 7 blank 8 blank 9 blank 10 Story CENTER: Character C haracter E xcellence Ow n ership nacity 11 T enacity E ntrepreneurship R elationship Example. Gas pressure by virial equation We have 3.0 mol of isopropanol vapor at 200 C in 4,000 cm 3 of volume. Experimental values for the virial coefficients of the vapor at 200 C are B = 388 cm 3 /mol and C = 26,000 cm 6 /mol 2 . Find the pressure for a) an ideal gas, b) a real gas with the virial equation Z = 1 + B/V + C/V 2 . 12 blank 13 Summary Calculus helps us with thermo! 14 C haracter E xcellence Ow n ership T enacity E ntrepreneurship R elationship Character....
