Question

1. Determine the specific entropy change,
s, for the following ideal gas processes by (i). integrating the polynomial expression cp(T) found in Table A-21/A-21E (ii). then by assuming a constant cp at the average temperature found in Table A-20/A-20E. (iii). finally, use the appropriate ideal gas table A-22/A-22E or A-23/A-23E. *A. Air at 98 kPa and 320 K goes to 953 K and 150 kPa? *B. Air at 82 psi and 550oF goes to 26 psi and 780oF?

Explanation / Answer

Positive entropy change means more disorder 2H2S(g)+2O2(g)----->2H2O(g)+2SO2(g) same # of molecules = no change in disorder 2. water vaporized when boiled gas more disordered than liquid + change 3. carbon dioxide gas dissolved in soda liquid less disorder - change 4. 2AL(s)+3Br2(l)---->2AlBr3(s) 5 molecules to 3 molecules less disorder -
