Why does your refrigerator give off so much heat?
The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization.
What form of energy does a refrigerator produce?
In a refrigerator, electrical energy is converted into mechanical energy by a motor. The motor drives a compressor, and this compresses and heats the refrigerant. Mechanical energy is converted into thermal energy in this process. The hot refrigerant is cooled in the cooling coils behind or beneath the appliance, and the cooler gas is "sprayed" through an expansion valve connected to the cooling coils inside the unit. The releasing of the pressure of the refrigerant allows expansion, and with expansion comes cooling.
Why does the gas in the refrigerator cause cooling on expansion?
Heat of the gas is lost as work done by the gas.
What is the gas used in refrigerator for cooling?
freon is the gas used in refrigator for cooling purpose
Where does the energy come from to warm the pipes at the back of the fridge?
Ammonia gas is compressed until it becomes very hot from the increased pressure. This heated gas flows through the coils behind the refrigerator, which allow excess heat to be released into the surrounding air.
Which gas is used for cooling refrigerator?
CFC gas is used for cooling refrigerator.

What is the function of hydrogen in an absorption refrigerator?
usually hydrogen or helium gas were choose as inlet gas/ carrier from evaporator to absorber coil. Inlet gas contribution toward total pressure in the system where according to formula to determine partial pressure in the system PTOTAL SYSTEM = P HYDROGEN (inlet gas ) + P AMMONIA (REFRIGERANT )
What should the low side refrigerator pressure be on a refrigerator while it is running?
70
Which gas filled in refrigerator?
Methane
Which gas is present in refrigerator?
amonia
How much did refrigerator cost in 1930?
An electric or gas refrigerator was a relative rarity in 1930. They were quite expensive compared to the average wage. A new gas refrigerator cost about $150 in 1930s dollars.
How does a refrigerator or freezer work to keep things cold?
Both the refrigerator and the freezer have fans to keep it at cold temperatures. PV=RT; A compressor raises the pressure of the gas volume V and temperature rises. A fan blows away the heat into the room. Then the gas pressure is dropped in the refrig cold room and the temperature drops in the cold room, PV=RT. The heat in the cold room heats up the gas and the volume goes to the compressorr again, ec,etc,etc.

How does an ice box differ from a refrigerator?
An icebox is exactly that - an insulated box, nothing more, nothing less, in which a block of ice was placed to cool the air (and contents). In the age before the electrical refrigerator, the icebox filled the same roll.A refrigerator is similar in appear and construction of the basic "box", but, rather than rely on a cold substance (ice) to cool the interior air, uses an electric pump to decompress one of several gases (formerly freon, now a variety of similarly-performing gases). These gases are decompressed by the refrigerator's main electrical pump, then piped through the main body of the 'frig. Due to the lower gas pressure, they are endothermic, which means, that as the gas expands back up to normal atmospheric pressure, it absorbs heat. The warm gas is then piped back into the electric pump, which decompresses the gas, in an exothermic reaction. Technically, a refrigerator is a simple heat pump; using the decompression/expansion of the gas to draw heat from inside the refrigerator and expelling that heat out into the surrounding air.
Why does the gas in the refrigerator cause cooling on expansion?
Heat of the gas is lost as work done by the gas.
Which gas is released by refrigerator?
The refrigeration unit is sealed, it does not release any gas.
