12. Solution to Chemistry Problem

14. Determine the change in entropy if 100*10-3 kg of water taken at 273 K is converted into steam at 390 K. The specific heat of evaporation of water at 373 K is 2263.8-103 J/kg; the specific heat capacity of liquid water is 4.2 J/(kg•K); the specific heat capacity of steam at constant pressure is 2.0*103 J/(kg•K).
