A fridge does not “create cold.” It pumps heat from inside the box to the room. A refrigerant cycles: evaporates inside (absorbs heat), is compressed, then condenses outside (releases heat). The back of the fridge feels warm because that heat is dumped into the kitchen.

You cannot cool a closed room by leaving the fridge door open — the heat pumped out plus motor waste heats the room overall.

Physics lessons in Model Town Lahore can use the kitchen fridge before abstract heat-engine diagrams.
