1. Heat Transfer Methods

Key Concepts & Definitions

  • Conduction: Heat transfer through direct contact between solids, where energy is passed from molecule to molecule without the movement of the material itself. (source)
  • Convection: Heat transfer through the physical movement of liquids or gases (fluids), involving the circulation of warmer and cooler areas. (source)
  • Radiation: Heat transfer through electromagnetic waves, which can occur through a vacuum or transparent media, without needing a medium for transfer. (source)
