Answer<br />
No, as for ANY spontaneous process, even in this<br />
case the entropy of the universe increases!<br />
Why<br />
Solidification of water is an exothermic process<br />
with heat of fusion of -6.88 kJ/mol. Hence the<br />
system (water) passes heat to the surroundings.<br />
Thus entropy change of system decreases,<br />
entropy of surrounding increases, thus change<br />
of entropy of the universe is positive.<br />
