Aheat pump has a coefficient of performance that is 60% of the carnot heat pump coefficient of performance. the heat pump is used to heat a home to 24.0°c during the winter with the low temperature reservoir at the outdoor temperature. at which outdoor temperature would it be more efficient to add the energy directly to the interior of the home than use it to run the heat pump? -154°c -40.0°c -4.00°c -83.4°c -25.2°c

Explanation:

Given

COP= 60 % of carnot heat pump

For heat added directly to be as efficient as via heat pump

the independent variable, or the one that is intentionally manipulated is the speed.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
