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

inserting the values


B)
Heat expelled is given as
Q' = W + Q
Q' = 800 + 1735
Q' = 2535 J
That's the description of a ground fault circuit interrupter (GFCI).
The choices you posted seem to belong to a different question.
Answer:
0 Kelvin
Explanation:
Atoms in absolute temperature get approximatelly motionless since 0 Kelvin is -273 degrees Celcius. The kinetic energy of atoms/particles in matter has the possible lowest value ( almost zero), so that there is nothing colder than 0 Kelvin.
