Question 63

Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Suppose that a roast turkey is taken from an oven when its temperature has reached Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Suppose that a roast turkey is taken from an oven when its temperature has reached and is placed on a table in a room where the temperature is . If is the temperature of the turkey after t minutes, then Newton's Law of Cooling implies that . This could be solved as a separable differential equation. Another method is to make the change of variable .
