Answer:
[tex]COP_{Heating}[/tex][tex]= \frac{T_{H}}{T_{H}-T_{C} }[/tex]
The temperature must be in Kelvin: [tex]degrees Celsius+273.15=K[/tex].
Explanation:
COP is similar to efficiency: [tex]\frac{what you get}{what you pay}[/tex] = [tex]\frac{energy from hot reservoir}{work needed for energy transfer}[/tex]
