No, leaving the door of a refrigerator open will not cool a room, but will actually make the room hotter. A refrigerator cools its own interior by pumping heat to the heat exchange coils in the back (some models do not have exposed heat exchange coils, but the sides or back of the refrigerator have coils just underneath them, and they get hot). Those heat exchange coils pump heat into the room. Since the process is not 100% efficient, the amount of heat produced includes a certain amount of waste heat. As a result, pumping heat from one part of the room to another part of the room results in a net increase in heat.
the second law of thermodynamics proves that heat always flows from hot to cold. It is hard to give good every day examples, since when you open the refrigerator door you feel cold but actually the room is warming the fridge.
No, the fridge puts as much heat out its back as it will put out the door.
the air in a fridge when you open the door gets hotter because you let the particles out
yes
That only works if the oven is ON .

No, although the short-term effect would be for the refrigerator air / freezer air to mix with and cool the air in the room.The function of refrigerator is a heat exchanger; it removes heat from the inside of the fridge and pumps it to the outside of the fridge.If we open the refrigerator door, it will remove the heat from the air that mixes inside, but then will exchange the heat back into the kitchen. That's why the room can't be cooled for a long period. In fact, due to waste heat, the room could become warmer once the refrigerator contents have reached room temperature.

Cold air. Cold air is heavier than warm air so when you open the fridge door the cold air 'drops' out of the fridge onto the floor.
Because the motor running the compressor is generating more heat than the compressor is cooling. Once you close the door the space being cooled is smaller and the compressor can keep up and overcome that heat from the motor.
No, for two reasons. First, the fridge door has to be closed to keep the air temperature inside the fridge cool enough to keep the foods cold and safe. Second, leaving the fridge door open causes the refrigerator to run more, costing more energy and running up the electric or gas bill.
No, you cannot ruin the refrigerator by opening and closing the door or by leaving the door open for a few minutes. Refrigerators do have a lifespan for the number of times the doors can be opened and closed before a hinge breaks or the seal is damaged, but this cycle can be in the millions - so it won't be affected with normal use. Each time you open and close the refrigerator, some cool air escapes and can mean that the compressor will have to run to get temperature back to where it should be. Leaving the door open for a few minutes does cool off the interior and things inside will begin to cool off as well. This will result in the refrigerator compressor having to run to get the temperature back down. A good refrigerator is designed to have the compressor go through these cycles many thousands of times. The only reason someone may be concerned with having the refrigerator work more would be the electric bill (it goes up, refrigerator compressors use a lot of power) or the refrigerator compressor has had problems previously.

The double door will usually work out better. You will be able to only open the compartment that you need, keeping the air in for the rest of the refrigerator.
yes
if its plugged in and when you open the door the light is on
