You open the refrigerator in your room and put in a case of room-temperature root beer. After an hour, the root beer is ice cold. If your room air did not exchange any heat with the outdoor air during that time, the room air will be
A) colder because the refrigerator reverses natural heating, so that things get colder rather than hotter.
B) colder because as the refrigerator struggles to cool the root beer, some of the cold it produces inevitably leaks out into the room as the result of imperfect insulation.
C) warmer because the refrigerator will have pumped heat out of the root beer and into the room air.
D) warmer because some of the heat from the root beer inevitably leaks out into the room as the result of imperfect insulation.
