● Energy stored in “hot” matter
Conduction (傳導)
● ***Transfer of thermal energy through substance by vibration of atoms within
substance

Convection (對流)
● ***Transfer of heat through fluids (liquids/gases) by upward movement of warmer,

● ***Another e.g.: at night, off-shore breeze (from land to sea), land cools down faster
than sea; in daytime, on-shore breeze (from sea to land), land heats up faster than
sea
Radiation (輻射)
● ***Thermal radiation: transfer of energy by infrared (IR) waves
