- English Word Thermomagnetism Definition Magnetism as affected or caused by the action of heat; the relation of heat to magnetism.
- English Word Thermometer Definition An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions.
- English Word Thermometric Definition Alt. of Thermometrical
- English Word Thermometrical Definition Of or pertaining to a thermometer; as, the thermometrical scale or tube.
- English Word Thermometrical Definition Made, or ascertained, by means of a thermometer; as, thermometrical observations.
- English Word Thermometrically Definition In a thermometrical manner; by means of a thermometer.
- English Word Thermometrograph Definition An instrument for recording graphically the variations of temperature, or the indications of a thermometer.
- English Word Thermometry Definition The estimation of temperature by the use of a thermometric apparatus.
- English Word Thermomultiplier Definition Same as Thermopile.
- English Word Thermopile Definition An instrument of extreme sensibility, used to determine slight differences and degrees of heat. It is composed of alternate bars of antimony and bismuth, or any two metals having different capacities for the conduction of heat, connected with an astatic galvanometer, which is very sensibly affected by the electric current induced in the system of bars when exposed even to the feeblest degrees of heat.
- English Word Thermoscope Definition An instrument for indicating changes of temperature without indicating the degree of heat by which it is affected; especially, an instrument contrived by Count Rumford which, as modified by Professor Leslie, was afterward called the differential thermometer.
- English Word Thermoscopic Definition Of or pertaining to the thermoscope; made by means of the thermoscope; as, thermoscopic observations.
- English Word Thermostat Definition A self-acting apparatus for regulating temperature by the unequal expansion of different metals, liquids, or gases by heat, as in opening or closing the damper of a stove, or the like, as the heat becomes greater or less than is desired.
- English Word Thermostatic Definition Of or pertaining to the thermostat; made or effected by means of the thermostat.
- English Word Thermosystaltic Definition Influenced in its contraction by heat or cold; -- said of a muscle.
- English Word Thermotaxic Definition Pertaining to, or connected with, the regulation of temperature in the animal body; as, the thermotaxic nervous system.
- English Word Thermotension Definition A process of increasing the strength of wrought iron by heating it to a determinate temperature, and giving to it, while in that state, a mechanical strain or tension in the direction in which the strength is afterward to be exerted.
- English Word Thermotic Definition Alt. of Thermotical
- English Word Thermotical Definition Of or pertaining to heat; produced by heat; as, thermotical phenomena.
