What's the difference between diffusion and media?

Diffusion


Definition:

  • (n.) The act of diffusing, or the state of being diffused; a spreading; extension; dissemination; circulation; dispersion.
  • (n.) The act of passing by osmosis through animal membranes, as in the distribution of poisons, gases, etc., through the body. Unlike absorption, diffusion may go on after death, that is, after the blood ceases to circulate.

Media


Definition:

  • (n.) pl. of Medium.
  • (n.) One of the sonant mutes /, /, / (b, d, g), in Greek, or of their equivalents in other languages, so named as intermediate between the tenues, /, /, / (p, t, k), and the aspiratae (aspirates) /, /, / (ph or f, th, ch). Also called middle mute, or medial, and sometimes soft mute.
  • (pl. ) of Medium

Example Sentences:
