If 1 mol of ice melts at its melting point of 273 K, the entropy change for the ice is 22.0 J/K. If the ice melts in someone’s hand at 34°C, what is the change in the entropy of the universe? Assume a final temperature for the water of 0°C. The enthalpy of fusion for ice is 6.01 kJ/mol.

a. +19.6 J/K d. –2.4 J/K
b. –19.6 J/K e. +41.5 J/K
c. +2.4 J/K
