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
Styrofoam cup is a good insulator because it is coated with foam
paper or foam cups
It is a good insulator of heat :)
The foam contains air, which is a poor conductor of heat.
Foam is made of material that a very low level of confuctivity
Foam is made of material that a very low level of confuctivity
insulator :)
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.
Because it absorbs the sound but not all of the sound. :)
