1. The coefficient of performance of a reversible heat pump cycle is always greater than the coefricient of performance of an irrevernable refrigeration cyele even though each operates between different thermal reserveirs. 2. A cycle where energy is iransferred by heat into the system undergoing the cyele from the cold body and energy is transferred by heat from the system to the hot body to maintain the temperature within a dwelling below that of the surroundings is called Heat pump cycle Refrigeration cycle c. Power cycle: d. A+B 3. In the gearbox, there is an internal irreversibility due to a. Spontaneous chemical reaction b. Elastic deformation c. Spontaneous mixing d. Friction. 4. May be there are irreversibilities within a system undergoing an externally reversible process. a. True sentence b. Wrong sentence 5. Significant irreversibilities present during operation of a household refrigerator include inelastic deformation, chemical reaction, and heat transfer. a) True sentence b. False, just include heat transfer c. False, just include chemical reaction d. False, just include chemical reaction and heat transfer 6. One statement of the second law of themodynamies recognizes that the extensive property entropy is produced within systems whencver no external iireversibilities are present. Ketvin-plank 3. True sentence False sentence 7. The violation of the Kelvin-Planck statement implies violation of the Clausius statement of the second law of thermodynamics. b. False, there is no relation between the two statements c. False, Clausius statement is focused on Celsius temperature scale d. Ealse, Entropy is related to Kelvin-Planck statement 8. All actual processes can be considered as irreversible and non spontaneous ones. True sentence b. Wrong sentence 9. If the entropy change of a process of a closed system is equal zero and its entropy transfer is less tan zero, this process is classified as, a. Impossible b. Possible c. Reversible (d) Irreversible e. Indeterminate 10. A Refrigeration cycle operates between hot and cold thermal reservoirs at 2000K and 1000$ respectively. If the coefficient of performance of the refrigeration cycle were 4.5, its mode of operation is Reversible b. Irreversible c. Impossible d. Cannot be detemined with the data provided
