Why refregerator is not used to cool up the rooms?
The refrigerator takes heat from one place and puts it somewhere else - it is in effect a "heat pump". What you propose can be done, if the heat the refrigerator takes out is taken outside the house. This is exactly what an air conditioner does. It is, in effect, a "refrigerator" especially adapted to cool rooms.
Is it possible to cool down a room on a heat summer day by leaving the refrigerator door open?
No, the fridge puts as much heat out its back as it will put out the door.
How does the failure of the compressor in a refrigerator affect the heat transfer cycle?
When the compressor fails, the high vapor pressure refrigerant is no longer condensed. Without a phase change of the refrigerant is refrigerator will not cool.
How is a refrigerator an example of a heat mover?
Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.
Can a room be cooled by leaving the door of refrigerator open?
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.
What does a refrigerator use to transfer heat from cool area to a warm area?
cool

Describe the process that occurs in a refrigerator?
what happens is that all the heat is taken out of the refrigerator, leaving it cool on the inside and warm on the outside.
How does a heat mover absorbs heat from cold air?
A good example of this process is a refrigerator. Electricity is used to power the refrigerator to keep it cool. The room that the fridge is in is warmer. Normally the warm air from the room should flow into the refrigerator until they are the same temperature. The heat mover, which is the refrigerator in this case, absorbs the heat the cooler air absorbs, and moves it back into the room. This keeps the fridge at a constant temperature.

How could a student test the effect of removing heat from a gas that is stored in a sealed container?
Cool the gas in a refrigerator

No, the fridge puts as much heat out its back as it will put out the door.
Why a refrigerator doesn't cool food inside it?
The room and the refrigerator are a closed system. The fridge, being a machine, has efficiency which is less than 1. Therefore it creates more "waste" energy which is released into the room than it cools the insides of the fridge.
What are the Five uses of thermostat in a refrigerator?
it is use to adjust the set point of the aircondition for cool and heat, fan also on and off.
In a refrigerator does the food cool when a vapor turns to liquid?
When vapor turns into a liquid, it emits heat which is then released outside into the kitchen allowing the interior of the fridge to remain cool.
Why cant opening the door of the refrigerator will cool the kitchen?
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.
