A refrigerator consumes an average 35W power to operate between temperature $-$10$^\circ$C to 25$^\circ$C. If there is no loss of energy then how much average heat per second does it transfer?
Solution
$${{{T_L}} \over {{T_H} - {T_L}}} = C.O.P. = {{{{dH} \over {dt}}} \over {{{dW} \over {dt}}}}$$<br><br>${{263} \over {35}} \times 35 = {{dH} \over {dt}}$<br><br>${{dH} \over {dt}} = 263$ watts
