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.
