Why are two changes of state of the refrigerant necessary to operate a refrigerator?

What are two changes of state of the refrigerant necessary to operate the refrigerator?
gas to liquid and liquid to gas
What is the function of the condenser coil in a refrigerator?
The condenser coil, sometimes coils depending on the model, rests outside of the refrigerator compartment. Refrigerant, in a gas form and very warm, travels to the condenser coil where it cools and condenses into a liquid form as it moves through each pass of the coil. Once in a liquid state, the refrigerant is stored in a reservoir until needed for the refrigeration cycle to begin again.
What state is refrigerant leaving receiver?
low pressure liquid
What happens to a refrigerant when it is above the saturation temperature?
it remains in a vapor state

What does AC compressor do?
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
How are changes of state an important parts of the way a refrigerator works?
cause
A substance used in cooling systems that transfers large amounts of energy as it changes state is called?
REFRIGERANT
What change of state occur when water changes to gas?
gas
What does the principle of catastrophism state?
geologic changes occur suddenly
What is the function of condencer in refrigerator?
Any refrigeration system (home air conditioner, refrigerator, automotive air conditioner...) uses the evaporation cycle of the refrigerant to remove heat from an object.The evaporation cycle of refrigeration systems is as follows:Refrigerant is compressed by the compressor. When the refrigerant is compressed the heat is forced into a smaller volume, raising the temperature of the refrigerant.The hotter refrigerant is then passed through a cooling coil, also called a condenser and air is passed across the hot coils, cooling the compressed refrigerant to room temperature, or close. The refrigerant, now under much higher pressure then changes state from a gas to a liquid.The refrigerant is then allowed to pass through an orifice, allowing the compressed refrigerant to expand. When the refrigerant expands it changes back to a gas, the temperature drops. The process is called "heat of vaporization".The chilled refrigerant is then passed through an expansion coil where something (air, water... whatever is being refrigerated) gets cooler.From there, the refrigerant is again compressed, starting the cycle over.As you can see, the condenser is essential to the refrigeration process. If the condenser develops a leak, the refrigerant is lost. If the condenser is kinked, refrigerant cannot get past. If air is blocked from passing over the condenser, the refrigerant cannot be cooled.
What is needed for a solid to sublime and what changes of state occur?
pressure and the change of state is chemical
What does ac condenser do?
Refrigerant enters the condenser as a high pressure vapor. In the condenser, the heated refrigerant is cooled by transferring its heat to the air which passes through the condenser fins, and it changes state to a liquid during this time.
What state of refrigerant leaving the receiver of a refrigerant system?
Liquid
What is the function of the condenser coil in a refrigerator?

Refrigerant, in a gas form and very warm, travels to the condenser coil where it cools and condenses into a liquid form as it moves through each pass of the coil.
