PS.5.1.3 (5.P.3.2) #1 Schoolnet (Conductors/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 allow heat or electricity to flow through it easily. Examples include rubber, wood, and plastic.

Front

Why is wood a good insulator?

Back

Wood does not conduct heat well, which means it stays cool to the touch even when in contact with hot objects.

Front

What property makes metals good conductors of heat?

Back

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

Front

What is the best material for cookware?

Back

A material that conducts heat evenly, such as stainless steel or copper, is best for cookware.

Front

Why do we use metal pans for cooking?

Back

Metal pans heat well and distribute heat evenly, which helps food cook properly.

Front

What happens to a metal wire in a light bulb?

Back

The metal wire heats up quickly and glows when electricity passes through it, producing light.

Front

What is the best material to store ice cream?

Back

Plastic is a good insulator and helps keep ice cream cold without getting too cold itself.

Front

How does heat transfer in conductors?

Back

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

Front

What is thermal conductivity?

Back

Thermal conductivity is a measure of how well a material conducts heat. High thermal conductivity means better heat conduction.
