Unformatted text preview: 3. a. Calculate S if 1 mol of liquid water is heated from 0 to 100C under constant pressure if C P,m = 75.291 J K 1 mol 1 . b. The melting point of water at the pressure of interest is 0C and the enthalpy of fusion is 6.0095 kJ mol 1 . The boiling point is 100C and the enthalpy of vaporization is 40.6563 kJ mol 1 . Calculate S for the transformation H 2 O( s , 0C) H 2 O( g , 100C). 4. One mole of H 2 O( l ) is compressed from a state described by P = 1.00 bar and T = 298 K to a state described by P = 800 bar and T = 450 K. In addition, = 2.07 10 4 K 1 and the density can be assumed to be constant at the value 997 kg m 3 . Calculate S for this transformation, assuming that = 0. You will need the Appendix in Levine, and see Section 4.6....
