convection

[fayebeth2121]

if a fridge has a freezer compartment at the top , explain how with the door closed , a convection current is set up in the fridge and how this ensures that the foods in the bottom comparment are kept cold ?

In a sentence: remember that warm air rises and cold air sinks.

Cold air is denser than cold air so gravity pulls it downwards setting up a convection current.

Oops! should have said cold air is denser than warm air.
