Answer:
Heat released into the room = 1300 J
Explanation:
CONCEPT:
According to second law of thermodynamics , heat cannot flow from a lower temperature to a higher temperature.But the refrigerator transfers heat from lower to higher temperature .For this , we have to do work on the refrigerator.
This work is used to transfer heat from lower to higher temperature.
Heat released into the room = Heat removed + work done
Heat released into the room = 800 +500
Heat released into the room = 1300 J
