Superheated water is liquid water that has been heated above its boiling temperature while still in the liquid state. As with supercooled water, superheated water is thermodynamically unstable and spontaneously vaporizes rapidly and irreversibly. 0.901 mol of liquid water are superheated to a temperature of 449 K. The normal boiling temperature is 373 K. Calculate the entropy changes of the system, surroundings, and universe when this superheated water is converted to water vapor at a constant pressure of 1.0 atm. The molar enthalpy of vaporization of water is 40.79 kJ molº?. The constant pressure molar heat capacities of liquid water and water vapor are 75.5 J mol? K and 34.4 ) mol? K , respectively. JK-1 Assys= AS surr As univ= K-1 K-1
