3. Calculate the change in the entropy of the system when heating 200*10-3 kg of water from 273 K to 390 K. The specific heat of evaporation of water at a temperature of 373 K is 2263.8*103 J/kg; the specific heat capacity of liquid water is 4.2*103 J/(kg*K), and the specific heat capacity of water vapor at constant pressure is 2.0*103 J/(kg*K).
