Question

Suppose you close the kitchen doors and windows and then leave the refrigerator door open. Heat from the warm room begins entering the refrigerator. (a) What happens to the heat that enters the refrigerator? Choose one answer only. it stays inside all of it plus extra heat is dumped back into the room some of it, but not all, is dumped back into the room all of it is dumped back into the room (b) What happens to the temperature of the kitchen? Choose one answer only. goes down goes up remains the same

Explanation / Answer

it stays inside all of it plus extra heat is dumped back into the room some of it, Because it depends up on the efficiency of the fridge.

Temperature increases. We know that the heat pump in the fridge pumps heat from the inside of the fridge into the room. This would not change the room temperature at all if the process were 100% efficient, but it is not: it takes electricity to run the motor, which winds up as heat, and warms the room.Well, its not possible to cool the room. Its something like this, the compressed gases in the tubes behind the refrigerator absorb the heat from inside the refrigerator and transfer the heat to the outside when they expand. So, the system will need a place to drain their heat. So if u close the doors and windows in a room, open up the fridge door, what happens is, the fridge draws heat from its front, drains it in the rear side. In the end, the heat will remain confined to the room.

But if we want to make fridge as a AC then keep the fridge on the room door's path, then, it will draw heat from the room, drain it in another room. Energy can neither ne created nor be destroyed, can only be transferred with a loss.
