Foam specific heat
WebApr 18, 2016 · We need to remember that Styrofoam is a brand name. It is actually a chemical compound polystyrene. Various values of its specific heat capacity are found. … WebApr 23, 2024 · Styrofoam is made mostly of air, meaning it is a poor conductor of heat, but an excellent convector. It traps the air in small pockets, blocking the flow of heat energy. This reduces both conduction and convection and makes Styrofoam a good insulator. On the other hand, conductors such as metal are poor insulators because energy flows …
