WebbPlace 75 grams of ice into each of 4 identical transparent plastic cups. Cover with lid. Cover the opening where the straw hole is with clay to make it airtight. 2. Insulate 3 of the cups with either aluminum foil, Styrofoam, or a plastic commercial insulator. Do not put any insulation on one of the cups. 3. Wait one hour. Webb23 juli 2024 · Plastics are insulators. Most plastics, however, are both thermal and electrical insulators, meaning they show high resistance to electrical current and are poor conductors of heat. Why is plastic known as non reactive? Answer: Plastic is non reactive because it does not let the flow of electrons. Is plastic non reactive?
