Conductors v Insulators

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat or electricity well. Examples include rubber, wood, and plastic.

Front

Why are metals good conductors of heat?

Back

Metals have free electrons that can move easily, allowing heat to transfer quickly.

Front

What happens to particles in a hot substance?

Back

Hot particles move faster and have more thermal energy compared to cold particles.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

Give an example of a good insulator found in the kitchen.

Back

An oven mitt is a good insulator that protects hands from heat.

Front

What is the purpose of rubber on frying pan handles?

Back

Rubber provides heat insulation, preventing the handle from getting too hot to touch.

Front

Which material is NOT an insulator?

Back

Pots and pans are not insulators; they are conductors.

Front

How does heat transfer through conductors?

Back

Heat transfers through conductors by the movement of free electrons that collide with other particles, transferring energy.

Front

What is the role of insulators in electrical wiring?

Back

Insulators prevent the flow of electricity outside the wires, ensuring safety and efficiency.
