thermo-, therm-, thermi-, -thermia, -therm, -thermal, -thermic, -thermias, -thermies, -thermous, -thermy
(Greek: heat, heating, heater, hot, warm)
The term heat is employed in ordinary language in different senses. Some scientists distinguish four principal applications of the term:
- Sensation of heat.
- Temperature, or degree of hotness.
- Quantity of thermal energy.
- Radiant heat, or energy of radiation.
2. An isotherm connecting places having the same temperature at the same moment of time.
2, A self-registering telethermometer.
2. An instrument, usually electrical, making such long-distance records.
2. An apparatus for determining temperature on which the reading is made at a distance from the object or subject being studied.
2. The property of a drug to elevate the temperature of the body.
2. The therapeutic use of hot air.
2. The ability to distinguish differences of temperature: As part of his science experiment, Noland learned to measure thermaesthesia in different animals.
3. A feeling in the body which recognizes heat and cold sensations: When Jason is either sweating or shivering, he is experiencing thermaesthesia.
Either the whole house or a single area may be heated to 150 degrees and more.
There is little scientific data on freezing and heating methods and both have drawbacks. Heating or thermagation is a non-chemical possibility but it can damage furniture, cosmetics, computers, tapes, CDs, foods, and any object that cannot withstand 140 to 150 degrees Fahrenheit; all must be removed from the premises and the price often is higher than fumigation.
Freezing uses liquid nitrogen to kill termites. It has proven to be an excellent non-toxic remedy in localized situations, but it is not particularly recommended for large areas.
Holes are drilled into the walls and liquid nitrogen under pressure is applied through the holes. Termites are 90 percent water and the nitrogen freezes them and they burst.
2. A localized air current that rises aloft when the lower atmosphere is heated enough to produce an instability over a certain area.
3. A rising current of relatively warm air, used by gliders and birds to gain height.
4. In meteorology, a localized air current that rises aloft when the lower atmosphere is heated by the earth’s surface enough to produce an absolute instability over a certain area; a common source of low-level clear-air turbulence.
5. Of, pertaining to, or of the nature of hot springs; of a spring, etc., (naturally) hot or warm; also, having hot springs.
6. Of or pertaining to heat; determined, measured, caused, or operated by heat.
