In winter, the COP value of a heat pump designed to try to keep the interior of the house at 25 ºC by drawing heat from the outdoor environment at -10ºC is 3.5. If 15000 kJ of heat needs to be given inside the house, what is the net electrical power that the heat pump will consume? A- 3647 kJ/hour B- 4286 kJ/hour C- 2497 kJ/hour D- 3846 kJ/hour E- 5166 kJ/hour

13- In winter, the COP value of a heat pump designed to try to keep the interior of the house at 25 ºC by drawing heat from the outdoor environment at -10ºC is 3.5. If 15000 kJ of heat needs to be given inside the house, what is the net electrical power that the heat pump will consume?
A- 3647 kJ/hour
B- 4286 kJ/hour
C- 2497 kJ/hour
D- 3846 kJ/hour
E- 5166 kJ/hour
(Note: This Turkish I'm using translate) orginal;
Kışın -10ºC’deki dış ortamdan ısı çekerek evin içerisini 25 ºC’de tutmaya çalışması için dizayn edilen bir ısı pompasının COP değeri 3.5 dir. Eğer evin içerisine 15000 kJ ısı verilmesi gerekiyorsa ısı pompasının harcayacağı net elektrik gücü nedir?
