Thermodynamics Physics Class 11 MCQ Question 2. The temperatures of inside and outside of a refrigerator are 273 K and 303 K respectively. Assuming, that the refrigerator cycle is reversible, for every joule of work done, the heat delivered to the surrounding will be nearly: (a) 10 J (b) 20 J (c) 30 J (d) 50 J. Answer. Answer: (c) 30 J. "/>. Video Transcript. Dear Students in the flying multiple choice question and secures we have asked that A reversible refrigerator work between two fixed temperature and the options are options as the same soap, whatever be the working substance, option B as its GOP increased for increasing substance with ill a top lee of the operation, Option C.. Following are the four processes of the Carnot cycle: In (a), the process is reversible isothermal gas expansion. In this process, the amount of heat absorbed by the ideal gas is qin from the heat source at a temperature of Th. The gas expands and does work on the surroundings. In (b), the process is reversible adiabatic gas expansion.
