If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 205j of energy to the room?

205 Joules of energy must be removed from the food

Explanation:
The first law of thermodynamics states that:
"The change in the internal energy of a closed system must be equal to the heat supplied to the system"
This law is actually a rephrasing of the law of conservation of energy which simply states that : "energy can neither be created nor destroyed, but can change from one form to another".

Now, in the given, we know that 205 J of energy were released from the system, this means that the change in the internal energy of the system was also 205 J.
In other words:
amount of energy removed from food = amount of energy released to the room

Therefore, the amount of energy removed from the food is 205 J.

Hope this helps :)

Wavelength divides in half and speed stays the same.
