Energy Transfer

Energy transfer is the transfer of energy from one object or material to another.

There are a few main ways that energy transfer occurs:

  • Radiant energy (radiation)
  • Heat conduction (travelling heat)
  • Convection (currents of warm air)
  • Electrical power transmission
  • Mechanical work (machines)

Famous quotes containing the words energy and/or transfer:

    The principle of avoiding the unnecessary expenditure of energy has enabled the species to survive in a world full of stimuli; but it prevents the survival of the aristocracy.
    Rebecca West (1892–1983)

    I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus transfer the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.
    Edgar Allan Poe (1809–1849)
