Ther`mo*dy*nam"ic (?), a. [Thermo- + dynamic.] (Physics) Relating to thermodynamics; caused or operated by force due to the application of heat.
Thermodynamic function. See Heat weight, under Heat.
Ther`mo*dy*nam"ics (?), n. The science which treats of the mechanical action or relations of heat.
Ther`mo*e*lec"tric (?), a. (Physics) Pertaining to thermoelectricity; as, thermoelectric currents.
Ther`mo*e`lec*tric"i*ty (?), n. [Thermo- + electricity: cf. F. thermoélectricité.] (Physics) Electricity developed in the action of heat. See the Note under Electricity.
Ther`mo*e`lec*trom"e*ter (?), n. [Thermo- + electrometer.] (Physics) An instrument for measuring the strength of an electric current in the heat which it produces, or for determining the heat developed by such a current.
Ther"mo*gen (?), n. [Thermo- + - gen.] (Old Chem.) Caloric; heat; regarded as a material but imponderable substance.
Ther`mo*gen"ic (?), a. (Physiol.) Relating to heat, or to the production of heat; producing heat; thermogenous; as, the thermogenic tissues.
Ther*mog"e*nous (?), a. [Thermo- + -genous.] (Physiol.) Producing heat; thermogenic.
Ther"mo*graph (?), n. [Thermo- + - graph.] (Physics) An instrument for automatically recording indications of the variation of temperature.
Ther*mol"o*gy (thr"ml"*j), n. [Thermo- + -logy.] A discourse on, or an account of, heat. Whewell.

Ther`mo*mag"net*ism (-mg"nt*z'm), n. [Thermo- + magnetism.] Magnetism as affected or caused by the action of heat; the relation of heat to magnetism.
Ther*mom"e*ter (thr*mm"*tr), n. [Thermo- + -meter: cf. F. thermomètre. See Thermal.] (Physics) An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompanied by proportional changes in their volumes or dimensions.
The thermometer usually consists of a glass tube of capillary bore, terminating in a bulb, and containing mercury or alcohol, which expanding or contracting according to the temperature to which it is exposed, indicates the degree of heat or cold by the amount of space occupied, as shown by the position of the top of the liquid column on a graduated scale. See Centigrade, Fahrenheit, and Réaumur.
