Is a foam cup A good conductor of heat?
It is a good insulator of heat :)
How is a foam coffee cup a good insulator?
The foam contains air, which is a poor conductor of heat.
How does foam wrap reduce radiation and conduction?
Foam wrap can reduce radiation and conduction because it is not a very good heat conductor.
How does air a bad conductor of heat help in winter?
Foam material makes good insulation.
Is foam conductor or insulator?
insulator :)
Is foam a good insulator or conductor?
insulator

Is foam a good conducter of heat?
In a foam there is a large gap between the conduction band and the valence of band in the atoms makng up the foam. If any object is to conduct electricity through it the gap between the conduction band amd the valance should be minimun or overlapping so that the electrons in the valance band can go into conduction band and conduct electricity

Whether plastic foam which contains pockets of air would be a good conductor or a good insulator.?
Because it fills heat slowly
Is plastic or Styrofoam the poorest conductor of heat?
The answer to this question depends on the magic word NIC. NIC is short for non-intercellular. This means that the tiny cells within the foam do not connect with each other. The foam does not soak up lots of water. You can't blow air through it. A plastic foam which is NIC is a very poor conductor of heat - a good insulator. A plastic foam which is intercellular is not a good conductor, but it is nowhere near as poor as NIC foam. Its best use is as a sponge for soaking up water.
Why do you use a foam cup instead of a beaker in an experiment?
foam cup is a poor conductor of heat! haha;] msg me!!
Is a foam coffee cup a conductor or a insulator?
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.
Why foam is used for insulation?
Foam can be a good insulator because it contains a lot of open gas spaces interrupted by fairly thin walls. The solid portions of the foam prevent much convection (air moving around carrying heat with it). Gas tends to be a lousy heat conductor, so all those air bubbles make the foam a poor conductor of heat - most of the conducted heat has to to travel through the limited solid structure of the foam (not much cross section for conduction).
