Question

Quizplus · Accepted Answer

According to the first law of thermodynamics, energy cannot be created or destroyed, only transferred. When the refrigerator is turned on and its door is left open, it begins to transfer heat from inside the refrigerator to the room. This transfer of heat increases the total internal energy of the room, causing the temperature to increase. Therefore, choice B is the correct answer.

Option A is incorrect because even though the room is thermally insulated, there is still energy being transferred to the room from the refrigerator.

Option C is incorrect because the transfer of heat from the refrigerator to the room increases the total internal energy of the room, causing the temperature to increase.

Option D is incorrect because the second law of thermodynamics is about the direction of heat transfer and not about the change in temperature.

Option E is incorrect because the second law of thermodynamics is about the direction of heat transfer and not about the change in temperature.
