A fridge typically works more efficiently when it is full because the items inside help to maintain a consistent temperature. When the fridge is empty, it has to work harder to cool the empty space.
Electromagnets work in a fridge by helping seal the fridge door shut. When the door is closed, the magnet creates a strong force that keeps the door in place and prevents warm air from entering and cool air from escaping. This helps to maintain the desired temperature inside the fridge for food preservation.
No, voltaic cells (most of what you call "batteries" are actually voltaic cells) work by oxidation and reduction. "Isothermal convection" is a term with which I am unfamiliar that seems like an oxymoron; if everything is the same temperature (isothermal) then convection won't occur, because temperature differences are what drive convection.
There is a magnet on the door of the fridge and this is attracted to the metal on the fridge. This closes the door. This method makes it easier to close refrigerator doors and also makes it more likely that you've actually closed the door.
The work done in lifting the fridge is equal to the force applied (700 N) multiplied by the distance moved (4 meters), which gives a total work of 2800 joules.

cold air sinks to the bottom of the fridge whilst the warm air rises
no it does not.
Convection ovens have a fan in them which circulates the air. That makes for faster cooking (20%)

When you unplug your fridge, it stops receiving power, which is needed for it to work. Check the power source and plug it back in to see if that resolves the issue.
you keep your scardox alien in the fridge for a day or if it doesn't work try 2 days.

they work in eg. compasses, fridge doors, and in some handbag clips.
Heat energy and a temperature difference.
