Question

You place a frozen pie in an oven and bake it for an hour. Then you take it out and let it cool. Describe how the temperature of the pie changes as time passes. Then sketch a rough graph of the temperature of the pie as a function of time.

Short answer

First, the temperature of the pie in the oven increases rapidly. And when it is taken out of the oven, it rapidly cools down to room temperature.

Step-by-step solution

Describe the change in temperature of the pie

When the pie is put into the oven, its temperature increases rapidly and reaches beyond the oven temperature. The pie remains at the oven temperature for some time. When the pie is taken out of the oven, its temperature decreases rapidly because of the large temperature difference and reaches room temperature.

Sketch the graph of temperature

The graph below represents the temperature change of the pie with the time elapsed.
