What's the difference between demonstrate and vacuum?

Demonstrate


Definition:

  • (v. t.) To point out; to show; to exhibit; to make evident.
  • (v. t.) To show, or make evident, by reasoning or proof; to prove by deduction; to establish so as to exclude the possibility of doubt or denial.
  • (v. t.) To exhibit and explain (a dissection or other anatomical preparation).

Vacuum


Definition:

  • (n.) A space entirely devoid of matter (called also, by way of distinction, absolute vacuum); hence, in a more general sense, a space, as the interior of a closed vessel, which has been exhausted to a high or the highest degree by an air pump or other artificial means; as, water boils at a reduced temperature in a vacuum.
  • (n.) The condition of rarefaction, or reduction of pressure below that of the atmosphere, in a vessel, as the condenser of a steam engine, which is nearly exhausted of air or steam, etc.; as, a vacuum of 26 inches of mercury, or 13 pounds per square inch.
