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:

    Two wooden tubs of blue hydrangeas stand at the foot of the stone steps.
    The sky is a blue gum streaked with rose. The trees are black.
    The grackles crack their throats of bone in the smooth air.
    Moisture and heat have swollen the garden into a slum of bloom.
    Pardie! Summer is like a fat beast, sleepy in mildew....
    Wallace Stevens (1879–1955)

    Coal is a portable climate. It carries the heat of the tropics to Labrador and the polar circle; and it is the means of transporting itself whithersoever it is wanted. Watt and Stephenson whispered in the ear of mankind their secret, that a half-ounce of coal will draw two tons a mile, and coal carries coal, by rail and by boat, to make Canada as warm as Calcutta, and with its comfort brings its industrial power.
    Ralph Waldo Emerson (1803–1882)

    For, ere Demetrius looked on Hermia’s eyne,
    He hailed down oaths that he was only mine,
    And when this hail some heat from Hermia felt,
    So he dissolved, and showers of oaths did melt.
    William Shakespeare (1564–1616)
