The coefficient of performance of a refrigerator is 5. If the temperature inside freezer is \( - 20^\circ C\), the temperature of the surroundings to which it rejects heat is.
371351
The inside and outside temperature of a refrigerator are \(273{\rm{ }}K\) and \(303{\rm{ }}K\) respectively. Assuming that refrigerator cycle is reversible, for every joule of work done the heat delivered to the surrounding will be
371352
A refrigerator with coefficient of performance 3 releases \(200 \mathrm{~J}\) of heat to a hot reservior. The work done on the working substance is
1 \(100\;J\)
2 \(\dfrac{100}{3} J\)
3 \(150\;J\)
4 \(\dfrac{200}{3} J\)
Explanation:
\(\frac{{200}}{W} = COP = 3 \Rightarrow W = \frac{{200}}{3}\,Joule.\)
