What's the difference between heat and thermogenic?

Heat


Definition:

  • (n.) A force in nature which is recognized in various effects, but especially in the phenomena of fusion and evaporation, and which, as manifested in fire, the sun's rays, mechanical action, chemical combination, etc., becomes directly known to us through the sense of feeling. In its nature heat is a mode if motion, being in general a form of molecular disturbance or vibration. It was formerly supposed to be a subtile, imponderable fluid, to which was given the name caloric.

  • (n.) High temperature, as distinguished from low temperature, or cold; as, the heat of summer and the cold of winter; heat of the skin or body in fever, etc.
  • (n.) Indication of high temperature; appearance, condition, or color of a body, as indicating its temperature; redness; high color; flush; degree of temperature to which something is heated, as indicated by appearance, condition, or otherwise.
  • (n.) A single complete operation of heating, as at a forge or in a furnace; as, to make a horseshoe in a certain number of heats.

  • (n.) Utmost violence; rage; vehemence; as, the heat of battle or party.
  • (n.) Agitation of mind; inflammation or excitement; exasperation.
