ICE CUBES MELTING IN A BEAKER<br />
(1 of 2)<br />
Water freezes at 0 deg C. or 32 deg F. at 1 atm<br />
Melting ice is favored by entropy but disfavored by enthalpy. The freezing of water is favored by enthalpy but disfavored by entropy. The entropy & enthalpy terms for both processes balance each other at 0 deg C.
