Heat Capacity
See also: Heat capacity and CalorimetryWhen a sample is heated, meaning it receives thermal energy from an external source, some of the introduced heat is converted into kinetic energy, the rest to other forms of internal energy, specific to the material. The amount converted into kinetic energy causes the temperature of the material to rise. The introduced heat divided by the observed temperature change is the heat capacity (C) of the material.
If heat capacity is measured for a well defined amount of substance, the specific heat is the measure of the heat required to increase the temperature of such a unit quantity by one unit of temperature. For example, to raise the temperature of water by one kelvin (equal to one degree Celsius) requires 4186 joules per kilogram (J/kg)..

Famous quotes containing the words heat and/or capacity:
“For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe anything but the perception.”
—David Hume (1711–1776)
“The terrifying message of gay liberation is that men are capable of loving their brothers. It should be sweet news to every woman in the world, for, if the capacity of men to love whom they have been taught to treat as competitors and enemies can transcend their education, the world can begin to heal.”
—Jane Rule (b. 1931)
