Question

What is the profile of the graph of temperature versus time, when water as a block ice is heated, and the temperature of the ice, water, and steam are periodically monitored?

Answer 1

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.

Answer 2

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`.
