Two identical bodies have temperatures \(277^{\circ} \mathrm{C}\) and \(67^{\circ} \mathrm{C}\). If the surroundings temperature is \(27^{\circ} \mathrm{C}\), the ratio of loss of heats of the two bodies during the same interval of time is (approximately)

  1. A 4:1
  2. B 8:1
  3. C 12:1
  4. D 19:1
Verified Solution

Answer & Solution

Correct Answer

(D) 19:1

Step-by-step Solution

Detailed explanation

\(\begin{aligned} & T_1=277^{\circ}=277+273=550 \mathrm{~K} \\ & T_2=67^{\circ} \mathrm{C}=67+273=340 \mathrm{~K} \end{aligned}\) Temperature of surrounding, \(T=27^{\circ} \mathrm{C}=27+273=300 \mathrm{~K}\)…
