Heat exchange mechanisms
Conduction - molecules or atoms exchange kinetic energy of directly through collisions
Convection - heat transfer via 3-step process: conduction, advection, & conduction
Radiation - objects loose or gain energy by emitting or absorbing electro-magnetic (EM) radiation
- Objects above 0°K emit EM radiation
- Energy content of radiation proportional to frequency & inversely proportional to wavelength
- Emitting & absorbing objects behave like black-bodies
