In a fridge, convection works by the movement of cold air sinking and displacing warm air as it rises. The cold air displaces the warm air from the interior of the fridge, absorbing heat in the process. This cycle helps maintain a consistent temperature inside the fridge for food preservation.
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%)
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.
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.
Electromagnets in a fridge work by using an electric current to create a magnetic field. This magnetic field attracts the metal armature on the fridge door, keeping it closed. When the electric current is turned off, the magnetic field dissipates, allowing the door to be opened. This mechanism ensures that the fridge door stays securely closed when not in use.
they work in eg. compasses, fridge doors, and in some handbag clips.
Heat energy and a temperature difference.
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.
