Thermal Energy & Heat Transfer Methods

[!] STUDY GUIDE: Big Ideas Use to answer form questions

1.Heat always transfers from warmer to cooler; 'cold' is absence of heat. Students often think cold transfers from cold objects to warm objects, but evidence from investigations shows otherwise. Use data from today's stations to identify which observations best support this understanding.

2.Temperature is average kinetic energy; heat is energy transferred due to temperature difference. Students often think temperature and heat are the same thing, but evidence from investigations shows otherwise. Use data from today's stations to identify which observations best support this understanding.

3.Insulators slow heat transfer; they don't create energy. Students often think insulators create warmth or coldness, but evidence from investigations shows otherwise. Use data from today's stations to identify which observations best support this understanding.

WRITE FOCUS QUESTION Your initial thinking

At a restaurant, a chef stirs boiling soup with a wooden spoon for minutes with no pain. A customer accidentally leaves a metal spoon in their bowl and burns their hand seconds later picking it up.

Why does a metal spoon get hot in soup but a wooden spoon doesn't?

DRAW CONCEPT MODEL Show your understanding visually

Cross-section: pot, metal spoon, wooden spoon. Particle dots (closer=more KE) + energy-transfer arrows at the soup–spoon interface. Label conduction, convection (soup), radiation (escaping heat). Show why one handle gets hot and one doesn't.

1. Cold flows from a cold object into a warm object, making the warm object cooler.

2. Temperature and heat are the same thing -- they both measure how hot something is.

F12345T

3. A wool blanket creates heat to keep you warm on a cold night.

F12345T

4. Heat always transfers from warmer objects to cooler objects until they reach the same temperature.

5. [Last week · C7W4] Exothermic chemical reactions create thermal energy from nothing — energy is added to the system.

F12345T

6. [Spiral · C1W2] When energy is 'used' by a device or transferred as heat, some of it disappears or is destroyed.
