Study Notes
Conduction
- Conduction involves direct heat transfer between substances in contact.
- Examples include heat conduction through metal or cooking food in a pan.
- Ice melting in a hand showcases conduction; thermal energy moves from hand to ice.
Convection
- Convection refers to heat transfer through fluids (liquids or gases) due to motion.
- Involves the circulation of fluid as warmer, less dense regions rise and cooler, denser regions sink.
- The Greenhouse Effect exemplifies convection; heat is trapped in the Earth's atmosphere.
Radiation
- Radiation is heat transfer that occurs through empty space, without needing a medium.
- It includes energy emitted in the form of electromagnetic waves.
- The Sun represents radiation as it emits heat and light to the Earth across the vacuum of space.
