A) \[11{}^\circ C\]
B) \[21{}^\circ C\]
C) \[31{}^\circ C\]
D) \[41{}^\circ C\]
Correct Answer: C
Solution :
coefficient of performance \[\beta =5\] \[{{\operatorname{T}}_{L}}=273-20=253K\]C \[{{\operatorname{T}}_{H}}=303.6K\] \[{{\operatorname{T}}_{H}}=303.{{6}^{o}}C\,\,\,\simeq {{31}^{o}}C\]\[\]You need to login to perform this action.
