Now, scientists have found that nanowires made of a certain isotope of silicon can conduct heat 150% better than natural silicon nanowires, potentially leading to drastically cooler computer chips. 2. These molecules then bump into nearby particles and transfer some of their energy to them. They are the good conductors of heat and electricity. weak, low melting point, poor conductor of heat. one suitable heat conductor is as good as another. Because of this weakness, the copper-core is usually covered with a nickel alloy to protect it. Metals conduct heat well for two reasons: metal ions pack very closely together in their molecular lattice, and electrons drifting through the metal carry kinetic energy around the lattice. Graphite, which is a good conductor of electricity, is an exception. Explain the meanings of malleable and ductile. Platinum is also a conductor of electricity, but less conductive than copper . Example - Copper, Aluminium. Answer: Materials which have good mobility of electrons are known as conductors and materials with less mobility of electrons are referred to as insulators. It has the highest thermal conductivity. Diamond is the leading thermally conductive material and has conductivity values measured 5x's higher than copper, the most manufactured metal in the United States. Comparing properties of alloys and pure metals. Diamond is made up of carbon atoms which are 4 way covalently bonded by each other which means no free electron thus no flow of electricity. 5. This exchange of matter might be a fluid, such as oil or water, or moving air. Bad conductors are those materials which do not allow electricity to pass through them easily. Metals are good conductors of heat and electricity while non-metals are poor conductors. Copper is a conductive material having a low resistance.
