A cool object is placed in a room that is maintained at a constant temperature of 20°C. The rate at which the temperature of the object rises is proportional to the difference between the room temperature and the temperature of the object. Let y = f (t) be the temperature of the object at time t; give a differential equation that describes the rate of change of f (t).
