I WONDER - Are All Metals Conductors?

The video tutorial discusses the properties of metals as conductors of heat and electricity. It highlights silver as the most conductive element but notes copper's widespread use due to its cost-effectiveness and availability. The concept of superconductors, which have zero electrical resistance, is introduced. The tutorial also explains why metals are excellent heat conductors, using the example of using wooden spoons in cooking to avoid heat conduction.

Which materials are considered the best conductors of heat?

• Plastics

• Metals

• Wood

• Glass

Why is copper more commonly used than silver for electrical wiring?

• Copper is more durable than silver.

• Copper is more conductive than silver.

• Copper is lighter than silver.

• Copper is cheaper and easier to source.

Which element is the most conductive of all?

• Silver

• Copper

• Aluminum

• Gold

What is a unique property of superconductors?

• They have zero electrical resistance.

• They have high electrical resistance.

• They are poor conductors of heat.

• They are non-metallic.

Why are wooden spoons preferred over metal spoons for cooking?

• Wooden spoons are better conductors of heat.

• Wooden spoons are more durable.

• Wooden spoons do not conduct heat well.

• Wooden spoons are cheaper.
