Question 5 / 5
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?

Select an answer

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

A

Heat flows from the hotter object to the colder one, so energy goes from the 175°C oven into the 25°C turkey until they approach the same temperature or the turkey is removed. (The exact equilibrium temperature depends on the oven/turkey heat capacities and heat losses — it won't spontaneously go above the oven's temperature.)
