Answer:

<em>14.07 units of joules is removed for each joules of electricity used</em>

Explanation:

The heated room temperature T_{c} = 61 °F

The outside temperature T_{h} = 98 °F

For conversion from fahrenheit to kelvin we use the equation

(32°F − 32) × 5/9 + 273.15

T_{c} = 289.26

T_{h} = 309.82

For air conditioning,

COP = \frac{T_{c} }{T_{h} -T_{c} }

COP = \frac{289.26 }{309.82 -289.26 }  = 14.07

This means that <em>14.07 units of joules is removed for each joules of electricity used</em>
