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.
A device that uses an outside energy source to transfer thermal energy from a cool area to a warm area is called a?
A device that transfers thermal energy from a cool region to a warm region is called a Heat Pump. Refrigerators are an example of this. So are many air conditioning units.
What does COP stand for from a thermodynamic stand point?
COP in thermodynamics usually refers to the Coefficient Of Performance(sometimes CP) andis the ratio of the heating or cooling provided over the electrical energy consumed.COPheating = |QH|/W = (|QC| + W)/WCOPcooling = |QC|/WwhereQC is the heat removed from the cold reservoirQH is the heat supplied by the hot reservoirThe COP provides a measure of performance for heat pumps that is analogous to thermal efficiency for power cycles. In the case of a refrigerator, the cold reservoir is the air in the room around the refrigerator and the hot reservoir is the interior of the refrigerator - counterintuitive as that may sound. In the case of the refrigerator, the refrigerant is compressed such that it is hotter than the room, thus making it a source of heat. Part of the energy comes from the interior of the refrigerator (QC) and the rest from the work done by the compressor. When a heat pump is used to warm a building, the outside air is the hot reservoir - even though it may be colder than inside the building. Once again, the fluid used in the heat pump is compressed so that it can dump heat into the building and then when expanded outside, it is cold enough to absorb energy from the outside air.
Can a Refrigerator be next to a heat water heater?
The refrigerator is a heat pump, taking heat from the inside and discharging it via the coils on the back of the cabinet. The coils lose heat mostly by air circulation. If you restrict the air circulation, the refrigerator will not work as well, since it cannot easily dump the heat it is transferring into the atmosphere. The baseboard heater will be creating hot air. If the hot air circulates behind the refrigerator, then the 'fridge will be trying to dump its hot air into another hot air stream. Ideally, the refrigerator should get an unobstructed flow of room temperature air. Worst case, the 'fridge motor will run for much longer than normal, and will drive up your power bill.
A heat pump has a cop rating of 2.5 to 1 if 200 watts of electricity are used to run the heat pump how many equivalent watts are produced?
19.a heat pump has a COP rating of 2.5 to 1. If 200 watts of electricity are used to run the heat pump, how many equivalent watts(heat) are produced?
Do the refrigerator get the heat out or cool in?
A refrigerator is a form of heat pump. It pumps heat out of something.
What is a Example of heat mover?
A refrigerator is an example of a heat mover.
What is an example of a heat mover?
A refrigerator is an example of a heat mover.
Is a refrigerator makes objects colder an example of the first law of thermodynamics?
The First Law of Thermodynamics is never violated, so yes (everything is an example of it...). In the case of a refrigerator, the inside of the refrigerator cools down, while the surroundings heat up. Also, energy is used to pump the heat; this is converted into additional heat. Total energy is, of course, conserved.
What type of device is a refrigerator?
a heat pump that uses work to move heat
Is a refrigerator an insulator?
No, a refrigerator is a type of heat pump, it takes heat out of the inside and rejects it to a heat exchanger on the back. I don't see how it could be called an insulator
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.
Is it true that heat can pass from cold bodies to hot bodies?
A heat pump can do that - for example, a refrigerator or an air conditioning system. This does require energy - heat will freely go only from hotter to colder bodies.
What devices is an example of a heat mover?

If a refrigerator is a heat pump that follows the first law of thermodynamics how much heat was removed from food inside of the refrigerator if it released 240J of energy to the room?
Not enough information. The refrigerator must also follow the Second Law.The energy released to the room is the energy removed from the room, PLUS the energy used by the refrigerator (for example, as electrical energy).
