What's the difference between convection and convention?

Convection


Definition:

  • (n.) The act or process of conveying or transmitting.
  • (n.) A process of transfer or transmission, as of heat or electricity, by means of currents in liquids or gases, resulting from changes of temperature and other causes.

Convention


Definition:

  • (v. i.) The act of coming together; the state of being together; union; coalition.
  • (v. i.) General agreement or concurrence; arbitrary custom; usage; conventionality.
  • (v. i.) A meeting or an assembly of persons, esp. of delegates or representatives, to accomplish some specific object, -- civil, social, political, or ecclesiastical.
  • (v. i.) An extraordinary assembly of the parkiament or estates of the realm, held without the king's writ, -- as the assembly which restored Charles II. to the throne, and that which declared the throne to be abdicated by James II.
  • (v. i.) An agreement or contract less formal than, or preliminary to, a treaty; an informal compact, as between commanders of armies in respect to suspension of hostilities, or between states; also, a formal agreement between governments or sovereign powers; as, a postal convention between two governments.

Example Sentences:
