Which group of materials is described as generally good heat conductors?

1. Conduction is heat transfer through direct physical contact. 2. Metals such as copper, aluminum, gold, and silver are named as good heat conductors. 3. Wood, plastic, and rubber are named as poor heat conductors, the opposite of what the question asks. 4. Glass, ceramic, wool, cotton, and foam are all used as insulating materials, not conductors. 5. So copper, aluminum, gold, and silver are correct. _Source: OpenStax Physics (CC BY 4.0), Ch 11 "Thermal Energy, Heat, and Work", section 11.2 Heat, Specific Heat, and Heat Transfer_
