To explain: Whether you could cool the kitchen by leaving the refrigerator open.

Answer to Problem 1FTD

No, it is impossible to cool the kitchen while leaving the refrigerator door open because the refrigerator cools some volume by removing heat from that volume and exhausting more heat at the back of the refrigerator. The kitchen is the refrigerating volume and the exhaust space at the same time if we open the refrigerator door.

The refrigerator works by using mechanical work to transfer heat from cooler interior to warmer surroundings.

It is impossible to cool the kitchen while leaving the refrigerator door open because the refrigerator cools some volume by removing heat from that volume and exhausting more heat at the back of the refrigerator. The kitchen is the refrigerating volume and the exhaust space at the same time if we open the refrigerator door.

Conclusion:

Therefore, it is impossible to cool the kitchen while leaving the refrigerator door open because the refrigerator cools some volume by removing heat from that volume and exhausting more heat at the back of the refrigerator. The kitchen is the refrigerating volume and the exhaust space at the same time if we open the refrigerator door.
