What else can I help you with?
If the coolant in a refrigerator was not compressed back into a liquid after it flowed through the refrigerator what would happen?
The fridge wouldn't get cold. The way the coolant works is as it passes through the fridge in liquid form it picks up the heat and turns to gas. This gas is then put through a compressor which forces it back into liquid thereby forfeiting its heat. And thereby removing the heat from the fridge.
Where does the heat go in a refrigerator?
In a refrigerator, heat is removed from the interior compartment and expelled into the surrounding room through the condenser coils located at the back or bottom of the refrigerator. This process allows the interior of the refrigerator to stay cool while the heat is dissipated into the room, helping to maintain a cold environment inside the fridge.
Does a refrigerator change heat into cold remove thermal energy from inside the refrigerator or cause thermal energy to disappear?
Thermal energy never disappears, but it can be moved from one place to another, which is what a refrigerator does. If you examine your refrigerator you will be able to observe that there are heat exchange tubes (usually on the back) which get hot as they pump heat from the interior to the exterior of the refrigerator.
Difference between heat rejection and heat absoarb in refrigerator?
Heat is absorbed by the refrigerant liquid inside the fridge, and rejected by the heat exchanger on the back of it.
Why is the back of a refrigerator painted black?
The back of a refrigerator is often painted black to help with heat absorption and dissipation. The black color helps the refrigerator's coils release heat more efficiently, aiding in the cooling process.
Why is the back of a refrigerator black?
Simply put a refrigerator works by moving heat from inside the fridge to outside the fridge. The grille at the back of a fridge is the place, where, just as with a car's radiator the unwanted heat is released. And black happens to be the color that is the best when it comes to releasing (and absorbing) energy.
Why is a room hot with a refrigerator in it?
A refrigerator generates heat as it works to cool the air inside, which can contribute to warming up the room. Additionally, the heat generated as the refrigerator motor operates can raise the overall temperature in the room. Proper ventilation and placement of the refrigerator can help moderate the temperature.
Does a refrigerator change heat into cold?
No, a refrigerator does not change heat into cold. It removes heat from inside the refrigerator and releases it outside, resulting in the cooling effect inside the refrigerator.
Where does the gas circulate the refrigerator walls to lose thermal energy?
The gas circulates through a series of coils on the back or bottom of the refrigerator, where it releases heat to the surrounding air. This process allows the gas to lose thermal energy and cool down before circulating back into the refrigerator to absorb more heat.
How does a heat mover absorb 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.

What is the function of a condenser in refrigerator?
The condenser cools the refridgerant. This turns it from a gas back to a liquid. Absorbing heat from the stored food causes the refridgerant to change from liquid to gas. This 'warm' gas is passed through the condenser, where the heat escapes. As the gas cools, it turns back to liquid for re-circulation. If you touch the coil at the back of a fridge - you'll see what I mean.
