depicting the temperature gradient.
6.The
metallic disc in a Lee's disc experiment is cooled after heating to a high
temperature. Assuming that the set up is kept in both at room temperature and
in a cold environment, compare the rate of cooling of the disc in ordinary
condition(room temperature) and in the cold condition by drawing suitable
graphs for the both.
