Question

Why a refrigerator is provided with insulated walls?

Answer 1

hey Frnd....
this is because the walls of refrigerator can't conduct electricity.
so we use insulated walls so that they can't conduct electricity n we are safe to touch the walls of refrigerator. and also they are made by insulators because they can't conduct heat as we know that heat energy is released by refrigerator. and if we use conductive walls they may conduct heat n may get hotter.
it's to harmful for us.
soooooo the conclusion is that we use insulated walls because they aren't harmful.
