It describes systems whose states are determined by thermal parameters, such as temperature, in addition to mechanical and electromagnetic parameters. (From Hawley's Condensed Chemical Dictionary, 12th ed),CSP: branch of chemistry concerned with heat and other energetic characteristics of chemical reactions and states.,NCI: The branch of physics concerned with the conversion of different forms of energy.
