1.	A refrigerator is to maintain eatables kept inside at `7^(@)C`. The coefficient opf performance of refrigerator if room temperature is `387^(@)C` isA. 15.5B. 16.3C. 20.1D. 9.03
Answer» Correct Answer - D Here , `T_(1)=38^(@)C=38 + 273 = 311 K` `T_(2)=7^(@)C = 7 + 273 =280 K` `therefore` coeffiecient of performance of the refrigeratior, `=(T_(2))/(t_(1)-T_(2))=(280)/(311-280)`=9.03
