WebSep 20, 2024 · What is refrigerator class 11th physics? 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. The temperature of the body can be lowered by extracting or removing the heat from the material or the body. WebApr 10, 2024 · While performing thermoelectric experiments, Peltier found there was an opposite phenomenon to the Seebeck Effect, in which thermal energy can also get absorbed in one dissimilar metal junction and dissipated at the other junction when an electric current flowed within the closed circuit. WebExamples of open thermodynamic systems include: -Water boiling in a pot without a lid (heat and steam, which is matter, escape into the air) -Turbines -Compressors -Heat exchangers -The human body Isolated Systems An isolated system is one where the work is not performed on or by the system.
