How does a Refrigerator work in simple terms?
How does a Refrigerator work in simple terms?
A Refrigerator works on 2 basic principals 1) As a liquid evaporates , it absorbs the heat from the surrounding areas . (A example, after having a bath , if you stand in the sun , you feel cold because the water is evaporating and absorbing the heat from your body.) 2) The opposite occurs if gas is compressed.
How does refrigerator work thermodynamics?
How they work. According to the Second Law of Thermodynamics, heat will always flow spontaneously from hot to cold, and never the other way around. A refrigerator causes heat to flow from cold to hot by inputting work, which cools the space inside the refrigerator.
What is refrigerator in physics class 11?
A refrigerator works on the principle of the second law of thermodynamics. This law is related to the extraction of heat from a body i.e. to lower the temperature of the body. Hence, a refrigerator is a device which works on the principle that evaporation of a liquid gives a cooling effect.
How do refrigerators work physics?
Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. When you release the contents into the lower pressure open space, it turns from a liquid to a gas.
How does a refrigerator work thermodynamics?
What is a refrigerator physics?
A refrigerator is a heat engine in which work is done on a refrigerant substance in order to collect energy from a cold region and exhaust it in a higher temperature region, thereby further cooling the cold region.
How do refrigerator compressors work?
In the first stage of the refrigeration cycle, refrigerant enters a compressor as a low-pressure vapor. The compressor compresses the refrigerant to a high-pressure vapor, causing it to become superheated. Once the refrigerant is compressed and heated, it leaves the compressor and enters the next stage of the cycle.

Complete answer: A refrigerator works on the principle of the second law of thermodynamics. This law is related to the extraction of heat from a body i.e. to lower the temperature of the body. Hence, a refrigerator is a device which works on the principle that evaporation of a liquid gives a cooling effect.
How does a fridge work thermodynamics?
How does a fridge work GCSE?
The coolant is a liquid as it enters the expansion valve. As it passes through, the sudden drop in pressure makes the liquid expand, cool, and turn into a gas. The coolant flows through thin pipes on the back of the fridge, giving out its heat and cooling back into a liquid as it does so.
How does a refrigerator use energy?
Refrigerators use electricity, which is then turned into kinetic energy by fans.
