What's the difference between diffuse and permeate?

Diffuse

Permeate


Definition:

  • (v. t.) To pass through the pores or interstices of; to penetrate and pass through without causing rupture or displacement; -- applied especially to fluids which pass through substances of loose texture; as, water permeates sand.
  • (v. t.) To enter and spread through; to pervade.

Example Sentences:
