Boiling water was placed in a freezer maintained at temperature -15 degrees Celsius to have the water just starting to freeze. Fifteen minutes after the said boiling water was placed in the freezer, the water was measured to be halfway to the goal in terms of the temperature. How many moreminutes should the water be left in the freezer just for the water about to freeze? Assume the system obeys Newton’s Law of Cooling and the surrounding temperature of the room did not change.
