You should find that the temperature of the ice increases until the first drops of liquid
appear and then the temperature remains the same, until all the ice is melted. You
should also find that when you cool water down from boiling, the temperature remains
constant for a while, and then starts decreasing.
N.B. Formulation of the answers to the questions above must be done with care and
accuracy. In fact, it should be like formulation of notes. Some of the above questions
will appear in the Practical Test to be administered on the 24th of April 2024.
