5-5 What is conduction?
Conduction: transfer of heat through solids
conductor: material that conducts heat easily
insulator: material that does not conduct heat easily
• Heat is transferred through solids by conduction.
• A conductor is a substance that allows heat to move through it easily.
• All metals are good conductors.
• Substances that do not conduct heat easily are called insulators.
• Insulators prevent heat from moving from place to place.
1. Define: What is conduction?
2. Identify: What substances are good conductors of heat?
3. Explain: Why are insulators used in houses?
Checking Concepts
1. How does heat travel by conduction?
2. Name two materials that are good conductors of heat.
3. What is an insulator?
4. Name two materials that are good insulators.
Thinking Critically
5. Infer: Explain how food in a pot gets heated by conduction.
6. Explain: How is a blanket an insulator?
