The room will warm up.
The fridge with the door left open will run pretty much continuously to try to cool the inside. Our fridge doesn't know the door is open, so it keeps running. The thermostat inside never senses that the inside has cooled, so it tells the compressor to stay on. The room will be cooled by the fridge, but remember that the compressor dumps heat out into the room all the while that it's running. And because the fridge is not 100% efficient, there will be more heat generated than there will be cooling. The result? The room will eventually warm up.
I would disagree partially with the above answer. 1) Efficiency is a term not really used for refrigerators. The term coefficient of performance is used because it can be and usually is greater than one (or greater than 100% in other words) and equals the heat removed from the inside of the fridge divided by the work input. 2) Now, if a perfect fridge was running on a Carnot cycle (no friction in the parts and other criteria) that gives the most cooling for the least amount of work, the room would still heat up as governed by the first law of thermodynamics. W=Heat from the condenser - heat from the evaporator or W+QL=QH. In this case all the terms are considered to be positive numbers. Clearly QH>QL which means the room is getting warmer.
Probably the easiest was to understand this is that work is going into the insulated room which means the overall energy and therefore temperature is going up.
yes
the air in a fridge when you open the door gets hotter because you let the particles out
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.
It can but dont leave your fridge open for too long!
No, the fridge puts as much heat out its back as it will put out the door.
yes
Yes but leave the door open to prevent mould build-up
Cold air in the refrigerator escapes and is replaced by warm humid room air. This usually triggers the refrigerator mechanism to cool that air, if you leave the door open too long you can waste lots of electricity.
If you have noticed the warm air blowing from behind your refrigerator, that is the heat that was in the air that is inside your refrigerator. If you leave the door open the air around the refrigerator will briefly feel cold, but it will warm back up and the food in the refrigerator will go bad.
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.
the air in a fridge when you open the door gets hotter because you let the particles out
When you leave the door open, the cool air flows out, and the warm air flows in. This means that the fridge will have to work harder to keep the food at the same temperature.
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.
if its plugged in and when you open the door the light is on
Try not to open the door too often, this is the same with the freezer, if you leave the freezer door shut, the goods will stay frozen longer than you think,
A bad and frustrating smell forms in and around the area where the fridge is located
Open the door and leave
