A refrigerator consumes an average 35 W power to operate between temperature -10° C to 25° C. If there is no loss of energy then how much average heat per second does it transfer ?

Question

A refrigerator consumes an average 35 W power to operate between temperature -10° C to 25° C. If there is no loss of energy then how much average heat per second does it transfer ? (A) 263 J/s (B) 298 J/s (C) 350 J/s (D) 35 J/s

( T L / T H - T L )= C . O . P .=(( dH / dt )/( dW ) dt ) (263/35) × 35=( dH / dt ) ( dH / dt )=263 watts

Q. A refrigerator consumes an average $35 W$ power to operate between temperature $- 1 0^{\circ} C$ to $2 5^{\circ} C$ . If there is no loss of energy then how much average heat per second does it transfer ?

263 J/s

298 J/s

350 J/s

35 J/s

$\frac{T _{L}}{T _{H} - T _{L}} = C . O . P . = \frac{\frac{d H}{d t}}{\frac{d W}{d t}}$
$\frac{263}{35} \times 35 = \frac{d H}{d t}$
$\frac{d H}{d t} = 263$ watts
