It is made if non conducting material and its structure traps air which is an excellent insulator in its own right
yes
yes
no i think i am right ( i hope )
Potato is also used for making batteries. So obviously, it is a good conductor.
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
insulator
is foam dirt an metal a 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
of course beause it is a type of foam
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.
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!
Foam rubber can be a good insulator due to its cellular structure that traps air pockets, providing thermal insulation. It also has good sound insulation properties, making it useful in dampening noise. However, its insulating effectiveness can vary depending on the specific type and density of the foam rubber.
Foam is a good insulator because air is not that good at conducting (meaning that it doesn't easily transport heat or cold) in relation to other materials. As foam consists of many tiny plastic pockets trapped with air it both stops convection and prevents conduction.
styrofoam ,bubble wrap ,polyurethane foam, fleece ,aluminiaum.
Plastic foam containing pockets of air is a good insulator. The air pockets hinder the transfer of heat or electricity, making it difficult for these forms of energy to pass through the material. This makes plastic foam with air pockets an effective insulator for keeping things warm or preventing electrical conduction.
