Heat

For the purposes of thermodynamics, it is convenient to define all energy while in transit, but unassociated with matter, as either heat or work. Heat is that form of energy in transit due to a temperature difference between the source from which the energy is coming and the sink toward which the energy is going. The energy is not called heat before it starts to flow or after it has ceased to flow. A hot object does contain energy, but calling this energy heat as it resides in the hot object can lead to widespread confusion. See Energy, Internal energy, Temperature, Thermodynamic principles

heat

[hēt]

(thermodynamics)

Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going; other types of energy in transit are called work.

heat

The form of energy that is transferred by virtue of a temperature difference between two bodies, the transfer being from the warmer to the cooler body.

Heat

a sensation of excessive warmth, usually confirmed by elevation of body temperature. Heat may be felt by some persons without a rise of body temperature; this can be caused by functional disturbances of the nervous system or by the introduction of certain medications (for example, nicotinic acid, magnesium sulfate, and calcium chloride) that cause dilatation of the blood vessels. Local sensation of heat can result from arterial hyperemia, a change in blood circulation, and increased metabolism in inflamed tissues.

(1) there must have been adequate provocation; (2) the killing must have been [in fact] in the heat of passion; (3) it must have been a sudden heat of passion--that is, the killing must have followed the provocation before there had been a reasonable opportunity for the passion to cool; and (4) there must have been a causal connection between the provocation, the passion, and the fatal act.(57) The underlying rationale of the provocation doctrine has also remained constant.

A Law of Her Own: The Reasonable Woman as a Measure of Man

Indeed, the entire idea of voluntary manslaughter (heat of passion crimes), that a circumstance could adequately provoke an otherwise reasonable person to commit an intentional(141) unlawful killing, "is a concession to human weakness."(142) The comments to the Model Penal Code mention only briefly that "a reasonable person does not kill even when provoked,"(143) but nonetheless recognize that sometimes an intentional killing may be attributable to the circumstances and not necessarily only the "moral depravity of the actor."(144)

Adequate provocation, individual responsibility, and the deconstruction of free will

The gist of a provocation claim is that "heat of passion reduces punishment because the actor is, unfortunately, like most humans."(156) So it is relevant to ask how most humans behave in a provocative circumstance.
