Question

Gregory is making a turkey for Thanksgiving by roasting it in his oven. The turkey started at a room temperature of 25°C, and the oven was preheated to 175°C. If Gregory accidentally turns off the oven after he places the turkey inside of it, then what will happen to the turkey?
A.
Thermal energy will flow from the oven into the turkey and continue to flow until they reach equilibrium at 100°C or the turkey is removed.

B.
Thermal energy will flow from the turkey into the oven and continue to flow until they reach equilibrium at 100°C or the oven is turned off.

C.
Thermal energy will flow from the oven into the turkey and continue to flow until the turkey reaches a temperature of 200°C.

D.
Thermal energy will flow from the turkey into the oven and continue to flow until the oven reaches a temperature of 200°C.

Answer 1

The correct answer is:

A. Thermal energy will flow from the oven into the turkey and continue to flow until they reach equilibrium at 100°C or the turkey is removed.

When the turkey is placed in the preheated oven, thermal energy will transfer from the oven (which is at a higher temperature) to the turkey (which is at a lower temperature) until both reach thermal equilibrium. However, since Gregory turned off the oven, the heat transfer will continue until the turkey gets warmer, but it would not reach 200°C—the turkey would not be able to exceed the maximum temperature of the oven while it’s off. Additionally, the oven itself would cool down over time.
