Why do refrigerators have double walls?
your question is wrong the refrigerator have many wall it depends it has a wall because to protect what is inside and the cool or the air con will be cool
How can the structure of the vacuum flask minimise energy transfer by conduction convection and radiation?
The flask has a double wall, with no air between the two walls (vacuum)- conduction. The walls are highly reflective silver- radiation. the flask has a small beck that is closed by a stopper or cap-convection.
How is conduction prevented in a thermos flask?
There are many ways this is done. It can be done by having a double walled thermos with either air, an insulator, or a vacuum between. A vacuum will prevent all conduction except where the two walls touch but requires stronger materials.
Why do your walls go dirty from your radiators?
Airborne dust and grease plus heat combine to paint stains on your walls. The best cure is not to have heat radiate from radiators so it is either a cold nose or clean walls. '

Why are Ice boxes provided with double walls?
Ice boxes are provided with double walls for strength. A double wall box has -- what it says --- a double wall. A single wall would not be as strong. I believe there are also some benefits of protecting the ice from the "elements".

Difference between load bearing and non-load bearing walls?
Non-load-bearing walls support only themselves; they are interior partition walls. They have a single top plate. While non-load-bearing walls might run perpendicular to floor and ceiling joists, they will not be aligned above support beams. As the name implies, load-bearing walls carry the structural weight of your home. Load-bearing walls in platform-frame homes will have double top plates. That is, two layers of framing lumber. Note: all exterior walls are load bearing; I got this from another site.
