Do describe the "work" that you believe is being done in order to move energy from the 41 degree object to the 50 degree object. In simple terms, this is the work being done to move energy from cool to warm in a refrigerator 1. The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator. 2. When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. 3. Now in liquid form at high pressure, the refrigerant cools down as it flows into the coils inside the freezer and the fridge. 4. The refrigerant absorbs the heat inside the fridge, cooling down the air. 5. Last, the refrigerant evaporates to a gas, then flows back to the compressor, where the cycle starts all over. So do describe the work being done to move energy from your 41 degree object to a 50 degree object.
