A beaker of water (100 g) at 20oC and 1 atm is heated to a temperature of 100oC by placing it on a heat reservoir at 100oC. The reservoir is at constant temperature. Data: Heat capacity for water: 4.184 J/g, Enthalpy of evaporation for water: 41 kJ/mol, Molar mass of water: 18 g/mol a. Calculate the entropy change of the beaker of water. b. Calculate the entropy change of the universe. c. Assume that water does not boil at 100oC. Calculate the entropy change of the universe.
