Calculate Î”S if 2.10 mol of liquid water is heated from 0.00 âˆ˜Cto 13.5 âˆ˜C under constant pressure if CP,m=75.3Jâ‹…Kâˆ’1â‹…molâˆ’1.
The answer the the problem above is 7.62 J/K
The melting point of water at the pressure of interest is 0.00âˆ˜C, and the enthalpy of fusion is 6.010 kJâ‹…molâˆ’1. The boiling pointis 100. âˆ˜C, and the enthalpy of vaporization is 40.65 kJâ‹…molâˆ’1.Calculate Î”S for the transformation of the same amount ofwater
H2O(s,0.00âˆ˜C) â†’H2O(g,100.âˆ˜C)
Can you help me solve the second question?
