| heat of evaporation | The heat absorbed in the evaporation of water, sweat or other liquid; for water it amounts to 540 cal/g at 100캜. Synonym: heat of vaporization. (05 Mar 2000) |
|---|---|
| heat of formation | The heat (expressed in calories or joules) absorbed or liberated during the (hypothetical) reaction in which a mole of a compound is formed from the necessary elements, in elemental form. (05 Mar 2000) |
| heat of fusion | <chemistry> The enthalpy change that occurs to melt a solid at its melting point. (09 Jan 1998) |
| heat of hydration | <chemistry> The enthalpy change associated with placing gaseous molecules or ions in water. (09 Jan 1998) |
| heat of solution | <chemistry> The enthalpy change associated with dissolving a solute in a solvent. (09 Jan 1998) |
| heat of vaporization | <chemistry> The energy required to vaporise one mole of a liquid at a pressure of one atmosphere. (09 Jan 1998) |
| heat prostration | 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 rash | An eruption of papules and vesicles at the orifices of sweat glands, accompanied by redness and inflammatory reaction of the skin. Synonym: heat rash, lichen infantum, lichen strophulosus, prickly heat, strophulus, summer rash, tropical lichen, lichen tropicus, wildfire rash. (05 Mar 2000) |
| heat rate | The amount of fuel energy required by a power plant to produce one kilowatt-hour of electrical output. A measure of generating station thermal efficiency, generally expressed in Btu per net kWh. It is computed by dividing the total Btu content of fuel burned for electric generation by the resulting net kWh generation. (05 Dec 1998) |
| heat rigor | Coagulation of muscle protein induced by heat. (05 Mar 2000) |
| heat stress disorder | A group of conditions due to overexposure to or overexertion in excess environmental temperature. It includes heat cramps, which are non-emergent and treated by salt replacement; heat exhaustion, which is more serious, treated with fluid and salt replacement; and heatstroke, a condition most commonly affecting extremes of age, especially the elderly, accompanied by convulsions, delusions, or coma and treated with cooling the body and replacement of fluids and salts. (12 Dec 1998) |
| heat transfer efficiency | Useful heat output released to the room divided by the actual heat produced in the firebox (17 Dec 1998) |
| heat treatment | In dentistry, a method of controlled temperature handling of metals so as to change the microscopic structure and thus the physical properties. See: temper, anneal. (05 Mar 2000) |
| heat urticaria | A form of physical or non-allergic urticaria initiated by heat (e.g., hot baths, physical exercise, pyrexia, exposure to sun or to a warm room) or by excitement; the rather distinctive lesions consist of pruritic areas 1 to 2 mm in diameter surrounded by bright red macules. Synonym: heat urticaria. (05 Mar 2000) |
| heat-curing resin | Resin that requires heat to initiate polymerization. (05 Mar 2000) |

| heat capacity |
(Also called thermal capacity.) The ratio of the energy or enthalpy absorbed (or released) by a system to the corresponding temperature rise (or fall). Heat capacities are defined for particular processes. For a constant volume process, where U is the internal energy of a system and T is its temperature. For a constant pressure process, where H is the system enthalpy. The heating rate, Q, for a constant volume process is whereas in a constant pressure process, See specific heat capacity.

| heat |
1. (Or heat content.) A form of energy transferred between systems, existing only in the process of transfer. 2. Same as enthalpy. Heat, used as a noun, is confusing and controversial in its scientific meaning. The differential of heat is considered imperfect in that its value depends on the process applied. In the thermodynamic definitions in this glossary, heat is avoided as a noun or adjective except where required by established use. ...
