I would think the apple would be rotten. I've never seen the inside of an apple that is naturally brown when cut open unless it was rotten.
If there is any food in the refrigerator, this would be a very bad idea - the food will have gone bad, since the temperature in the refrigerator would reach room temperature in a couple of days.If there is no food in the refrigerator, I suppose it would save money to turn it off.
I think the answer would be a lemon because an apple can go a while i don't know about a lemon!
An apple could make you sick because it is rotten or has unwanted pesticide chemicles which cause a reaction in your body that make you feel sick.
It would eventually cool to the ambient temperature of the refrigerator which is warmer than a freezer. Therefore it would reduce to being chilled rather than frozen, effectively defrosting, but slower than it would have done outside the refrigerator
In my opinion, probably an apple, because lemons have a lower pH which makes it hostile to more of the common microorganisms. But you might want to do the experiment yourself.
Refrigerators should be set at 40°F maximum.
That will depend upon the condition of the apple when placed on the counter, the ambient temperature and humidity, and the apple's pedigree. Some varieties keep longer than others. Some do better without refrigeration than others. But all apples do best under refrigeration.
If an apple is left in sunlight, it will be rotten in 4 days minimum. the sunshine is what will make it rot faster.
Because of the very low temperature inside a freezer, the sudden temperature change in the bulb when it switches on would make it pop.
Assuming the room is completely sealed, with no air flow in or out, the room temperature would go up. According to my college chemistry professor, refrigerators can only cool small cubic areas of air. However the motor that is running the refrigerator produces measurably more heat, and due to the door being open would run continuously to try to keep the refrigerator cool. The small amount of cool air coming out of the refrigerator would be no match for the heating effect of the motor, thereby raising the room temperature.
All metals will expand and contract to some degree depending on the temperature.
