F

• freezing - phase transition from liquid to solid
• Faraday constant - a unit of electrical charge widely used in electrochemistry and equal to ~ 96,500 coulombs.

It represents 1 mol of electrons, or the Avogadro number of electrons: 6.022 × 1023 electrons. F = 96 485.339 9(24) C/mol

• Faraday's law of electrolysis - a two part law that Michael Faraday published about electrolysis
  • the mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity transferred at that electrode
  • the mass of an elemental material altered at an electrode is directly proportional to the element's equivalent weight.
• frequency - number of cycles per unit of time. Unit: 1 hertz = 1 cycle per 1 second
