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.

Famous quotes containing the word heat:

    The Soul rules over matter. Matter may pass away like a mote in the sunbeam, may be absorbed into the immensity of God, as a mist is absorbed into the heat of the Sun—but the soul is the kingdom of God, the abode of love, of truth, of virtue.
    Ralph Waldo Emerson (1803–1882)

    Friendship is evanescent in every man’s experience, and remembered like heat lightning in past summers.
    Henry David Thoreau (1817–1862)

    Red river, red river,
    Slow flow heat is silence
    No will is still as a river
    Still.
    —T.S. (Thomas Stearns)
