Transfer of thermal energy outcomes11 objectives
- Recognize and provide examples of effective thermal conductors and ineffective thermal conductors (thermal insulators).
- Understand that convection is a significant method of energy transfer in liquids and gases.
- Explain the process of convection in liquids and gases.
- Explain thermal conduction in solids through atomic or molecular vibrations and the movement of delocalized electrons in metals.
- Clarify convection in liquids and gases based on changes in density.
- Recognize that thermal energy transfer via thermal radiation does not need a medium and primarily occurs through infrared radiation.
- Discuss how surface color (black or white) and texture (dull or shiny) influence the emission, absorption, and reflection of thermal radiation.
- Identify and explain some common applications and effects of conduction, convection, and radiation in everyday life.
- Understand that the Earth's temperature is influenced by the radiation it absorbs and emits.
- Outline experiments designed to differentiate between effective and ineffective emitters of thermal radiation.
- Outline experiments aimed at distinguishing between effective and ineffective absorbers of thermal radiation.
