Problem P. 4824. (March 2016)

P. 4824. The water of a lake in winter becomes colder and colder. Finally it freezes, and the width of the ice is getting thicker. Supposing that the air temperature is \(\displaystyle -20~{}^\circ\)C, sketch the graph of the temperature at a certain moment as the function of the depth measured from the top of the ice cover down to the bottom of the lake.
