Transferencia de calor – ¿Sabías que?

The video explains the concept of thermal conductors and insulators. It highlights that metals are good thermal conductors, which means they can transfer heat efficiently. In contrast, materials like wood and plastic are thermal insulators, which is why they are used for utensils to prevent heat transfer.

What is a key characteristic of metals that makes them useful in heat transfer?

• They are flexible.

• They are thermal conductors.

• They are lightweight.

• They are magnetic.

Which of the following materials is a thermal conductor?

• Plastic

• Glass

• Metal

• Wood

Why are wooden utensils preferred for stirring hot food?

• They are cheaper than metal utensils.

• They are easier to clean.

• They are thermal insulators.

• They are more durable.

What property of plastic makes it suitable for use in kitchen utensils?

• It is a thermal conductor.

• It is a thermal insulator.

• It is transparent.

• It is biodegradable.

Which material would you choose to prevent heat transfer?
