Question
(a) Find the change in entropy of the H2O molecules when 3.66 kilograms of ice melts into water at 273 K. (in J/K)
(b) Find the change in entropy of the H2O molecules when 3.66 kilograms of water changes into steam at 373 K. (in J/K)
(c) On the basis of the answers to parts (a) and (b), discuss which change creates more disorder in the collection of H2O molecules.

(a)
Q = (mass)(latent heat of fusion)
Q = m(h_fusion)
Q = (3660g)(333J/g) = 1218.78 KJ
T(K) = 273.15 = 273.15K
deltaS = 1218,780J / 273K
deltaS = 4464.40 J/K
(b)
Q = (mass)(latent heat of vaporization )
Q = m(h_vaporization)
Q = (3660g)(2258J/g) = 8264.28 KJ
T(K) = 373K
deltaS = 8264,280J / 373K
deltaS = 22156 J/K
(c)
Entropy is measure of diorderderness.
Since entropy change of vaporization is higher than that of fusion, vaporization of water molecules creates more disorder.
