If you leave the door open, heat is merely recycled from the room into therefrigerator, then back into the room. A net room temperature increase wouldresult from the heat of the motor that would be constantly running to move energy around in a circle.

The system will try to attain a state of equilibrium and in this process there will be a slight decrease in the room temperature leading to rise in temperature of refrigerator.... this flow will continue until the equilibrium state is attained.

Attempt All sub parts from each question.If we turn on our electric oven, and it will warm up the room. Keeping the oven door open, the room gets warm even faster. This is obvious since the purpose of an oven is to make things hot. But the opposite is not true of a refrigerator. Running the refrigerator makes the room warmer. If the door is kept open, the room gets warm up even faster. The first rush of cold air may cool things down a little, but in the long run, the room will get warmer. To see why, we need to think of heat as energy and cold as a lack of energy. The stove produces heat, but the refrigerator can't actually produce cold. All the refrigerator does is move heat, or energy, from one place to another. As the food inside the refrigerator loses its heat or, in other words, gets colder that heat warms up the room A refrigerator is an open system that dispels heat from a closed space to a warmer area, usually in the room. By dispelling the heat from this area, it decreases the temperature inside, allowing food and other items to remain cool. Refrigerators appear to violate the second law of thermodynamics. But actually they do not. Physicists call this kind of system a "heat pump." According to the Second Law of Thermodynamics, heat always flows from hot to cold, and not in the other way around. A refrigerator causes heat to flow from cold to hot by inputting work, which cools the space inside it.It does this by following the steps below:• Work is inputted (Win) which compresses a coolant, increases its temperature above the room temperature.• Heat flows from coolant into the room (QH) reducing the temperature of the coolant.• The coolant expands and it cools down below the temperature inside the refrigerator.• Heat flows from the refrigerator to the coolant (QC) decreasing the temperature inside.So, the heat pump in refrigerator needs energy to run. So while it is busy in moving energy out of the refrigerator and into the room, it also draws more energy in the form of electricity. Since some of that energy is released as heat, the room gets warmer.For refrigerators, a manufacturer would want to make the area colder while doing as little work as possible. By doing little work to cool the appliance, the refrigerator can stay at the desired temperature while using less electricity. The number that describes this idea is known as the coefficient of performance, K, which is essentially a measure of efficiency.The higher this value is, the better the refrigerator, because it means that less work is being done to cool down the refrigerator.Q.
