Conductors and insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper and gold.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, wood, and plastic.

Front

Which material is the best conductor of electricity?

Back

Gold is considered one of the best conductors of electricity.

Front

What state of matter is generally a better insulator?

Back

Liquids and gases are generally better insulators than solids.

Front

Why are metals good conductors?

Back

Metals are good conductors because their particles are closely packed together, allowing energy to transfer easily.

Front

What is an example of a good insulator used in homes?

Back

Fiberglass is a common insulator used in homes to keep heat in or out.

Front

What happens to the conductivity of materials when they are heated?

Back

Generally, the conductivity of conductors increases with heat, while the conductivity of insulators decreases.

Front

Why do we use metal pans for cooking?

Back

Metal pans are used for cooking because they are good conductors of heat, allowing food to cook evenly.

Front

What is the role of insulators in electrical wiring?

Back

Insulators protect us from electric shock by preventing electricity from escaping the wires.

Front

Can you name a liquid that is a good conductor?

Back

Saltwater is a good conductor of electricity.
