What's the difference between pressure and thermodynamics?

Pressure


Definition:

  • (n.) The act of pressing, or the condition of being pressed; compression; a squeezing; a crushing; as, a pressure of the hand.
  • (n.) A contrasting force or impulse of any kind; as, the pressure of poverty; the pressure of taxes; the pressure of motives on the mind; the pressure of civilization.
  • (n.) Affliction; distress; grievance.
  • (n.) Urgency; as, the pressure of business.
  • (n.) Impression; stamp; character impressed.
  • (n.) The action of a force against some obstacle or opposing force; a force in the nature of a thrust, distributed over a surface, often estimated with reference to the upon a unit's area.

Thermodynamics


Definition:

  • (n.) The science which treats of the mechanical action or relations of heat.

Example Sentences:

  • (1) From the previously observed results of preferential interactions for salting-out salts with proteins, it was shown that the free energy of the protein is increased by addition of the salts and this unfavorable free energy is smaller for the proteins bound to the columns because of their smaller surface area exposed to solvent; i.e., the bound form of the proteins is thermodynamically more stable.
