What's the difference between absorb and hydrophobic?

Absorb


Definition:

  • (v. t.) To swallow up; to engulf; to overwhelm; to cause to disappear as if by swallowing up; to use up; to include.
  • (v. t.) To suck up; to drink in; to imbibe; as a sponge or as the lacteals of the body.
  • (v. t.) To engross or engage wholly; to occupy fully; as, absorbed in study or the pursuit of wealth.
  • (v. t.) To take up by cohesive, chemical, or any molecular action, as when charcoal absorbs gases. So heat, light, and electricity are absorbed or taken up in the substances into which they pass.

  • (a.) Of or pertaining to hydrophobia; producing or caused by rabies; as, hydrophobic symptoms; the hydrophobic poison.
