Answer:
Explanation:
A)
W = work done by the freezer = 800 J
Q = heat removed from the freezer = 1735 J
Q' = Heat expelled into the room
Coefficient of performance is given as
[tex]\beta = \frac{Q}{W}[/tex]
inserting the values
[tex]\beta = \frac{1735}{800}[/tex]
[tex]\beta = 2.2[/tex]
B)
Heat expelled is given as
Q' = W + Q
Q' = 800 + 1735
Q' = 2535 J
