| heat apoplexy | A severe and often fatal illness produced by exposure to excessively high temperatures, especially when accompanied by marked exertion. It can manifest by elevated body temperature, lack of sweating, hot dry skin, and neurologic symptoms; unconsciousness, paralysis, headache, vertigo, confusion. In severe cases very high fever, vascular collapse, and coma develop. Synonym: heat apoplexy, heat hyperpyrexia, malignant hyperpyrexia, thermic fever. (05 Mar 2000) |

| heat capacity | <chemistry> The amount of energy required to raise the temperature of an object by one degree Celsius (or Kelvin), it is represented by the symbol C and is given in units of J/K. (09 Jan 1998) |
| heat coagulation test | A test for measurement of protein in urine; albumin and globulin are coagulated by heat at an acid pH, and the amount of turbidity present provides a qualitative estimation of the degree of proteinuria. (05 Mar 2000) |
| heat cramp | A form of heat illness that results from profuse sweating and loss of body salts (sodium). Heat cramps are manifest by painful spasms of abdominal and skeletal muscles. (27 Sep 1997) |
| heat cramps | Muscle spasms induced by severe exertion in intense heat, accompanied by considerable pain; sometimes related to salt deficiency, hyperventilation, or overindulgence in alcohol. Synonym: myalgia thermica. (05 Mar 2000) |
| heat-curing resin | Resin that requires heat to initiate polymerization. (05 Mar 2000) |
| heat exhaustion | A form of heat illness that results when the victim is dehydrated (fluid depleted). Common symptoms include: fatigue, lightheadedness, nausea, vomiting, headache, rapid heartbeat and lowered blood pressure. (27 Sep 1997) |
| heat hyperpyrexia | A severe and often fatal illness produced by exposure to excessively high temperatures, especially when accompanied by marked exertion. It can manifest by elevated body temperature, lack of sweating, hot dry skin, and neurologic symptoms; unconsciousness, paralysis, headache, vertigo, confusion. In severe cases very high fever, vascular collapse, and coma develop. Synonym: heat apoplexy, heat hyperpyrexia, malignant hyperpyrexia, thermic fever. (05 Mar 2000) |
| heat illness | A general term which describes three forms of heat related injury: heat cramps, heat exhaustion and heatstroke. (27 Sep 1997) |
| heat instability test | A test for the presence of unstable haemoglobins; fresh red blood cells lysed in distilled water develop a precipitate within one hour at 50캜 if unstable haemoglobin is present. (05 Mar 2000) |
| heat-labile | Destroyed or altered by heat. (05 Mar 2000) |
| heat lamp | A lamp that emits infrared light and produces heat; used to apply topical heat to the skin. Synonym: thermolamp. (05 Mar 2000) |
| heat oedema | Oedema caused by excessively high external temperature. (05 Mar 2000) |
| heat of combustion | The quantity of heat liberated per gram-molecular weight when a substance undergoes complete oxidation. (05 Mar 2000) |
| heat of compression | Heat produced when a gas is compressed. (05 Mar 2000) |
| heat exchanger |
Typically a grouping of parallel metal surfaces that maintain separation between two fluids while transferring heat from the hot fluid to the cooler fluid. In combustion systems, thermal energy is transferred from the hot exhaust gases to a heat transfer fluid that can be water, air, thermal oil or an antifreeze solution.
