Plastic foam consists of bubbles containing air or gas. Those bubbles are poor conductors of heat, and reduce the transfer of heat from warmer to cooler areas.

Why Does filling a cavity with foam reduce heat loss even further?
Because foam has many little air pockets, which reduce heat loss. Also, air is an insulator which means it is a poor conductor. Hope that helped!
How does a plastic box help to reduce heat loss?
Plastic is an insulator therefore it is a poor conductor of heat. A plastic box will therefore be able to keep a lot of heat on the inside.

What materials prevent heat loss for convection conduction and radiation?
conductor
What can I do to conserve energy loss on hot water pipes?
You can insulate the hot water pipes with spiral-wrap fiberglass insulation, foam tube insulation, or fiberglass pipe covers. These will all help reduce heat loss.
How does the foam reduce heat loss?
Foam contains pockets of trapped air which prevents conduction.
Why is plastic foam good at reducing heat loss?
It fills in spaces where air can penetrate and your conditioned air can escape. It is also great for keeping insects from entering your home.

Why is plastic foam good at reducing heat loss through walls?
I think it´s becaus the foam is in, principle, a solid with a great quantity of minuscule boubles of air. The heat reducing effect happens thanks to the iar inside the boubles. The material that forms the boubles absorbs a certain amount of heat, and when you apply heat to the exterior, it has to heat the material first then the heat transfer from the material to the air in the bouble. So that effect stacks up subsequently with the next layer of boubles, and the next and so on. Hope I helped you! :-)
How could having foam walls be good for the environment?
They reduce heat loss through the walls, hence you need less fuel (directly or at the power-station) to heat the building and maintain the temperature for a given heat rise and time.
What materials prevent heat loss for convection conduction and radiation?
conductor
Why are foam filled cavity walls are better than air filled cavity walls in reducing heat loss?
Foam is a good insulator- this means that it traps still air and prevents heat travelling and being lost. Heat is lost more easily through the air in air-filled cavity walls as the air is not kept still.

Is precipitation heat loss or heat gain?
heat loss
How does the thermos maintain heat?
A real one is a vacuum flask (or better: two flasks with a vacuum between them) - and so the only heat loss is via radiation (except at the cap). But most today are simply foam insulation.
