What is heat?

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:

    Genius is present in every age, but the men carrying it within them remain benumbed unless extraordinary events occur to heat up and melt the mass so that it flows forth.
    Denis Diderot (1713–1784)

    The hotel was once where things coalesced, where you could meet both townspeople and travelers. Not so in a motel. No matter how you build it, the motel remains the haunt of the quick and dirty, where the only locals are Chamber of Commerce boys every fourth Thursday. Who ever heard the returning traveler exclaim over one of the great motels of the world he stayed in? Motels can be big, but never grand.
    —William Least Heat Moon [William Trogdon] (b. 1939)

    Glories, like glow-worms, afar off shine bright,
    But looked to near, have neither heat nor light.
    John Webster (1580–1625)
