The solid-liquid transition temperature for water at normal atmospheric pressure is 0'C.

Explanation:

Melting points are a temperature, affected by pressure, but not by the surrounding temperature.

For the reaction.....H_2O(s) rightleftharpoons H_2O(l)........

Explanation:

You might remember the experiment you did in the laboratory in this context....

H_2O(s)rightleftharpoonsH_2O(l)

....where temperature is plotted against time....typically you get..

In the presence of ICE and water, the temperature remains constant at 0 ""^@C. In the presence of water and steam, the temperature remains constant at 100 ""^@C.
