A refrigerator works between \(4^o C\) and \(30^o C.\) It is required to remove \(600\) calories of heat every second in order to keep the temperature of the refrigerated space constant. The power required is ....... \(W\) (Take \(1\, cal \,=\, 4.2\, Joules\,)\)
- A \(23.65\)
- B \(236.5\)
- C \(2365\)
- D \(2.365\)
Answer & Solution
Correct Answer
(B) \(236.5\)
Step-by-step Solution
Detailed explanation
\(Given,\,{T_2} = {4^ \circ }C = 277\,K,{T_1} = {30^ \circ }C = 303\,K\) \({Q_2} = 600\,cal\,per\,second\)
