| 1. classification 2. insulate 3. semiconductor 4. particle 5. conduction | a. The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. b. A solid substance that has conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits. c. The action or process of classifying something according to shared qualities or characteristics. d. Any of various fundamental subatomic and most basic constituents of matter, including those that are the smallest, and those that transmit one of the four fundamental interactions in nature (gravitational, electromagnetic, strong, and weak). e. Prevent the passage of electricity to or from (something) by covering it in nonconducting material. |
