Samuel Johnson's Dictionary

  1. Heatnoun

    Etymology: heat, Hæt, Saxon; heete, Danish.

    Heat is a very brisk agitation of the insensible parts of the object, which produces in us that sensation from whence we denominate the object hot; so what in our sensation is heat, in the object is nothing but motion. John Locke.

    The word heat is used to signify the sensation we have when we are near the fire, as well as the cause of that sensation, which is in the fire itself; and thence we conclude, that there is a sort of heat in the fire resembling our own sensation: whereas in the fire there is nothing but little particles of matter, of such particular shapes as are fitted to impress such motions on our flesh as excite the sense of heat. Isaac Watts.

    The sword which is made fiery doth not only cut by reason of the sharpness which simply it hath, but also burn by means of that heat which it hath from fire. Richard Hooker, b. v.

    After they came down into the valley, and found the intolerable heats which are there, and knew no means of lighter apparel, they were forced to begin the custom of going naked. Francis Bacon, New Atlantis.

    Mark well the flow’ring almonds in the wood;
    The glebe will answer to the sylvan reign;
    Great heats will follow, and large crops of grain. Dryden.

    The heats smiths take of their iron are a blood-red heat, a white flame heat, and a sparkling or welding heat. Joseph Moxon.

    The continual agitations of the spirits must needs be a weakening of any constitution, especially in age; and many causes are required for refreshment betwixt the heats. Dryden.

    I’ll strike my fortune with him at a heat,
    And give him not the leisure to forget. John Dryden, Aurengz.

    Feign’d zeal, you saw, set out the speedier pace;
    But the last heat, plain dealing won the race. Dryden.

    It has raised animosities in their hearts, and heats in their faces, and broke out in their ribbans. Joseph Addison, Freeholder.

    They seeing what forces were in the city with them, issued against the tyrant while they were in this heat, before practices might be used to dissever them. Philip Sidney, b. ii.

    The friend hath lost his friend;
    And the best quarrels, in the heat, are curst
    By those that feel their sharpness. William Shakespeare, King Lear.

  1. HEAT

    High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity explosively formed penetrator (EFP) jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD). The EFPs jet effect is purely kinetic in nature; the round has no explosive or incendiary effect on the target. As they rely on the kinetic energy of the EFP jet for their penetration performance, HEAT warheads do not have to be delivered with high velocity, as an armor-piercing round does. Thus they can be fired by lower-powered weapons that generate less recoil. The performance of HEAT weapons has nothing to do with thermal effects, with HEAT being simply an acronym.


  1. heat

    Heat is a form of energy associated with the movement of atoms or molecules. It is typically transferred between systems or objects in various states such as solid, liquid, or gas. This transfer usually occurs from a region with higher temperature to another with lower temperature, often leading to a temperature change or phase transition in the receiving object or system.

  18. Etymology: [OE. heten, AS. htan, fr. ht hot. See Hot.]


  1. Heat

    In physics and chemistry, heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways, among them conduction, radiation, and convection. Heat is not a property of a system or body, but instead is always associated with a process of some kind, and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously, and is always accompanied by an increase in entropy. In a heat engine, internal energy of bodies is harnessed to provide useful work. The second law of thermodynamics states the principle that heat cannot flow directly from cold to hot systems, but with the aid of a heat pump external work can be used to transport internal energy indirectly from a cold to a hot body. Transfers of energy as heat are macroscopic processes. The origin and properties of heat can be understood through the statistical mechanics of microscopic constituents such as molecules and photons. For instance, heat flow can occur when the rapidly vibrating molecules in a high temperature body transfer some of their energy to the more slowly vibrating molecules in a lower temperature body.

Heat′-spot, a spot on the surface of the body where a sensation of heat is felt; Heat′-ū′nit, amount of heat required to raise a pound of water one degree.—Latent heat, the quantity of heat absorbed when bodies pass from the solid into the liquid, or from the liquid into the gaseous, state; Mechanical equivalent of heat, the relation between heat and work—viz. the amount of molecular energy required to produce one heat-unit; Specific heat, the number of heat-units necessary to raise the unit of mass of a given substance one degree in temperature. [A.S. hǽto, heat, hát, hot; Ger. hitze.]

The Standard Electrical Dictionary

  1. Heat

    A form of kinetic energy, due to a confused oscillatory movement of the molecules of a body. Heat is not motion, as a heated body does not change its place; it is not momentum, but it is the energy of motion. If the quantity of molecular motion is doubled the momentum of the molecules is also doubled, but the molecular mechanical energy or heat is quadrupled. As a form of energy it is measured by thermal units. The calorie is the most important, and unfortunately the same term applies to two units, the gram-degree C. and the kilogram-degree C. (See Calorie.) Calories are determined by a calorimeter, q. v. Independent of quantity of heat a body may be hotter or colder. Thermometers are used to determine its temperature. Heat is transmitted by conduction, a body conducting it slowly for some distance through its own substance. Bodies vary greatly in their conductivity for heat. It is also transmitted by convection of gases or liquids, when the heated molecules traveling through the mass impart their heat to other parts. Finally it is transmitted by ether waves with probably the speed of light. This mode of transmission and the phenomena of it were attributed to radiant heat. As a scientific term this is now dropped by many scientists. This practice very properly restricts the term "heat" to kinetic molecular motion. The mechanical equivalent of heat is the number of units of work which the energy of one unit quantity of heat represents. (See Equivalents, Mechanical and Physical.)

  4. Marshall Shepherd:

    Study after study finds discernible fingerprints of climate change in contemporary heat waves, most people know that summer is also the most uncomfortable in terms of heat and humidity. Basic physics relationships explain why a warmer climate will likely mean more oppressive heat indices and heat-related health issues.

    Excessive heat puts exposed working populations at greater risk from heat-induced stresses and undermines growth by compromising productivity, vulnerable groups need significant support to tackle rising heat in the workplace.
