1) a. What is the entropy change if two mole of liquid water is heated from 20 C to 100 C under constant pressure? Cp=75.5 J/mol*K over this temperature interval. b. Calculate (delta)r S^o for following process. H2O (G,100 C, 1 atm) --> H2O (s,0 C, 1 atm) (delta)r H fus= 6025 J/mol (delta)r Hvap= 40.7 kj/mol 2) Calculate the following a. Two moles of an ideal gas at 0 C expand (isothermally and reversibly from 10 to 40 liters. Calculate q,w, (delta) U, (DELTA) h AND (DELTA) S. B. Two moles of an ideal gas expand isothermically against a constant opposing pressure of 1 bar from 5 to 45 liters. Calculate q,w, (delta) U, (DELTA) h AND (DELTA) S.
