Web24 sep. 2024 · Styrofoam is about 98% air. It traps the air in its small pockets. Styrofoam has millions of small air bubbles trapped inside the foam. Since air is a bad conductor of heat Styrofoam efficiently prevents heat transfer. Air is a mixture of gases, and it is not a good conductor or a radiator. WebHi Mehran- Tinkle was right to assume that good electrical conductors are also good heat conductors, as described by the Wiedemann-Franz law. You raise some other good points, though. That same electrical conductivity makes the aluminum highly reflective.
