Melting


Definition:

  • (p. pr. & vb. n.) of Melt
  • (n.) Liquefaction; the act of causing (something) to melt, or the process of becoming melted.
  • (a.) Causing to melt; becoming melted; -- used literally or figuratively; as, a melting heat; a melting appeal; a melting mood.

Example Sentences:

  • (1) We’re learning to store peak power in all kinds of ways: a California auction for new power supply was won by a company that uses extra solar energy to freeze ice, which then melts during the day to supply power.
