The same root is the source of O.E. hat "hot" and hæða "hot weather." The verb is from O.E. hætan, from P.Gmc. *khaitijanam. Meaning "a single course in a race" is from 1663, perhaps from earlier fig. sense of "a single intense effort" (c.1380), or meaning "run given to a horse to prepare for a race" (1577). Meaning "sexual excitement in animals" is from 1768. Meaning "trouble with the police" attested by 1920. Heat wave "period of excessive hot weather" first attested 1893.

heat[hiːt]verb
(sometimes withup) to make or become hot or warm Example: We'll heat (up) the soup; The day heats up quickly once the sun has risen.
Internal energy that is transferred to a physical system from outside the system because of a difference in temperature and does not result in work done by the system on its surroundings. Absorption of energy by a system as heat takes the form of increased kinetic energy of its molecules, thus resulting in an increase in temperature of the system. Heat is transferred from one system to another in the direction of higher to lower temperature. See also thermodynamics. See Note at temperature.
In physics, a form of energy associated with the movement of atoms and molecules in any material. The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as heat. (Seeinfrared radiation.)
Ca*pac"i*ty\, n.; pl. Capacities (-t[i^]z). [L. capacitus, fr. capax, capacis; fr. F. capacit['e]. See Capacious.]1. The power of receiving or containing; extent of room or space; passive power; -- used in reference to physical things. Had our great palace the capacity To camp this host, we all would sup together. --Shak. The capacity of the exhausted cylinder. --Boyle. 2. The power of receiving and holding ideas, knowledge, etc.; the comprehensiveness of the mind; the receptive faculty; capability of undestanding or feeling. Capacity is now properly limited to these [the mere passive operations of the mind]; its primary signification, which is literally room for, as well as its employment, favars this; although it can not be dented that there are examples of its usage in an active sense. --Sir W. Hamilton. 3. Ability; power pertaining to, or resulting from, the possession of strength, wealth, or talent; possibility of being or of doing. The capacity of blessing the people. --Alex. Hamilton. A cause with such capacities endued. --Blackmore. 4. Outward condition or circumstances; occupation; profession; character; position; as, to work in the capacity of a mason or a carpenter. 5. (Law) Legal or noral qualification, as of age, residence, character, etc., necessary for certain purposes, as for holding office, for marrying, for making contracts, will, etc.; legal power or right; competency. Capacity for heat, the power of absorbing heat. Substances differ in the amount of heat requisite to raise them a given number of thermometric degrees, and this difference is the measure of, or depends upon, what is called their capacity for heat. See Specific heat, under Heat. Syn: Ability; faculty; talent; capability; skill; efficiency; cleverness. See Ability.
Heat\, n. [OE. hete, h[ae]te, AS. h?tu, h?to, fr. h[=a]t hot; akin to OHG. heizi heat, Dan. hede, Sw. hetta. See Hot.]1. A force in nature which is recognized in various effects, but especially in the phenomena of fusion and evaporation, and which, as manifested in fire, the sun's rays, mechanical action, chemical combination, etc., becomes directly known to us through the sense of feeling. In its nature heat is a mode if motion, being in general a form of molecular disturbance or vibration. It was formerly supposed to be a subtile, imponderable fluid, to which was given the name caloric. Note: As affecting the human body, heat produces different sensations, which are called by different names, as heat or sensible heat, warmth, cold, etc., according to its degree or amount relatively to the normal temperature of the body. 2. The sensation caused by the force or influence of heat when excessive, or above that which is normal to the human body; the bodily feeling experienced on exposure to fire, the sun's rays, etc.; the reverse of cold. 3. High temperature, as distinguished from low temperature, or cold; as, the heat of summer and the cold of winter; heat of the skin or body in fever, etc. Else how had the world . . . Avoided pinching cold and scorching heat! --Milton. 4. Indication of high temperature; appearance, condition, or color of a body, as indicating its temperature; redness; high color; flush; degree of temperature to which something is heated, as indicated by appearance, condition, or otherwise. It has raised . . . heats in their faces. --Addison. The heats smiths take of their iron are a blood-red heat, a white-flame heat, and a sparking or welding heat. --Moxon. 5. A single complete operation of heating, as at a forge or in a furnace; as, to make a horseshoe in a certain number of heats. 6. A violent action unintermitted; a single effort; a single course in a race that consists of two or more courses; as, he won two heats out of three. Many causes . . . for refreshment betwixt the heats. --Dryden. [He] struck off at one heat the matchless tale of "Tam o'Shanter." --J. C. Shairp. 7. Utmost violence; rage; vehemence; as, the heat of battle or party. "The heat of their division." --Shak. 8. Agitation of mind; inflammation or excitement; exasperation. "The head and hurry of his rage." --South. 9. Animation, as in discourse; ardor; fervency. With all the strength and heat of eloquence. --Addison. 10. Sexual excitement in animals. 11. Fermentation. Animal heat, Blood heat, Capacity for heat, etc. See under Animal, Blood, etc. Atomic heat (Chem.), the product obtained by multiplying the atomic weight of any element by its specific heat. The atomic heat of all solid elements is nearly a constant, the mean value being 6.4. Dynamical theory of heat, that theory of heat which assumes it to be, not a peculiar kind of matter, but a peculiar motion of the ultimate particles of matter. Heat engine, any apparatus by which a heated substance, as a heated fluid, is made to perform work by giving motion to mechanism, as a hot-air engine, or a steam engine. Heat producers. (Physiol.) See under Food. Heat rays, a term formerly applied to the rays near the red end of the spectrum, whether within or beyond the visible spectrum. Heat weight (Mech.), the product of any quantity of heat by the mechanical equivalent of heat divided by the absolute temperature; -- called also thermodynamic function, and entropy. Mechanical equivalent of heat. See under Equivalent. Specific heat of a substance (at any temperature), the number of units of heat required to raise the temperature of a unit mass of the substance at that temperature one degree. Unit of heat, the quantity of heat required to raise, by one degree, the temperature of a unit mass of water, initially at a certain standard temperature. The temperature usually employed is that of 0[deg] Centigrade, or 32[deg] Fahrenheit.
Heat\, v. t. [imp. & p. p. Heated; p. pr. & vb. n. Heating.] [OE. heten, AS. h?tan, fr. h[=a]t hot. See Hot.]1. To make hot; to communicate heat to, or cause to grow warm; as, to heat an oven or furnace, an iron, or the like. Heat me these irons hot. --Shak. 2. To excite or make hot by action or emotion; to make feverish. Pray, walk softly; do not heat your blood. --Shak. 3. To excite ardor in; to rouse to action; to excite to excess; to inflame, as the passions. A noble emulation heats your breast. --Dryden.
Heat\, v. i. 1. To grow warm or hot by the action of fire or friction, etc., or the communication of heat; as, the iron or the water heats slowly. 2. To grow warm or hot by fermentation, or the development of heat by chemical action; as, green hay heats in a mow, and manure in the dunghill.
