Air or any sort of gas is not that good in conducting heat in relation to other materials, since foam consists of many bubbles with trapped gas it both stops convection by simply being in position, and prevents conduction of heat through it, due to the gas inside.
insulator
is foam dirt an metal a good insulator
No, foam insulation products acts as an insulator.
This depends on the type of foam. There have been made foam that actually conduct electricity. This is a choice made in the manufacturing of the foam. Most foam in mattresses and the like does not conduct electricity. Moisture however can change the mattresses conductivity drastically.
stira foam is a better insulator because it will keep it warm
Styrofoam, along with most other expanded plastics, is a very poor insulator of heat and electricity, thereby making a foam coffee cup a very good insulator.
paper or foam cups
Foam is made of material that a very low level of confuctivity
Foam is made of material that a very low level of confuctivity
Foam can be either a conductor or an insulator, depending on its composition and density. Some foams, like foam insulating materials, are designed to be insulators and can trap air pockets to prevent the transfer of heat or electricity. Other foams, like conductive foams used in electronics, are designed to conduct electricity.
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!
of course beause it is a type of foam
