Example Question #1 : Determine The Relationships Between Energy Transfer And Type Of Matter
What is a conductor?
A conductor is a substance that does NOT transfer electric or heat energy easily.
A conductor is a substance that makes electrons move in a line like a train
A conductor is a substance that transfers electric or heat energy easily.
A conductor is a substance that transfers motion easily
A conductor is a substance that transfers electric or heat energy easily.
A conductor is a substance that transfers electric or heat energy easily.
Some types of matter transfer energy more easily than others. These substances are called “conductors.” An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. Some examples of conductors are copper, steel, gold, aluminum, and brass. If a substance does NOT transfer energy efficiently, it is called an insulator. Some common insulators are: Glass, Air, Plastic, Rubber, Porcelain, and Wood.
Example Question #2 : Determine The Relationships Between Energy Transfer And Type Of Matter
Which of these is an example of a conductor?
grass
wood
water
mud
water
The answer is water because electric and heat energy move easily through it.
