Conductors and insulators

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to flow through it easily.

Front

Give an example of a good conductor.

Back

Copper is a good conductor of electricity.

Front

Give an example of a good insulator.

Back

Rubber is a good insulator.

Front

Why are metals generally good conductors?

Back

Metals have free electrons that can move easily, allowing heat and electricity to pass through.

Front

What happens to the particles in a conductor when it is heated?

Back

The particles in a conductor vibrate faster, allowing heat to transfer quickly.

Front

What is the role of air as an insulator?

Back

Air is a poor conductor of heat, which makes it a good insulator.

Front

How does the state of matter affect conductivity?

Back

Solids are usually better conductors than liquids and gases because their particles are closer together.

Front

What is thermal conductivity?

Back

Thermal conductivity is a measure of how well a material conducts heat.

Front

What is electrical conductivity?

Back

Electrical conductivity is a measure of how well a material allows electricity to flow through it.
