Kelvin temperature scale
Kelvin temperature scale a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero , or 0°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of -273.15° on the Celsius temperature scale . The Kelvin ... Read more
William Thomson Kelvin, 1st Baron
William Thomson Kelvin, 1st Baron 1824-1907, British mathematician and physicist, b. Belfast. He was professor of natural philosophy at the Univ. of Glasgow (1846-99). He is known especially for his work on heat and electricity. In thermodynamics his work of coordinating the theories of heat held... Read more
Celsius temperature scale
Celsius temperature scale , temperature scale according to which the temperature difference between the reference temperatures of the freezing and boiling points of water is divided into 100 degrees.

absolute zero
absolute zero the zero point of the ideal gas temperature scale, denoted by 0 degrees on the Kelvin and Rankine temperature scales, which is equivalent to -273.15°C and -459.67°F. For most gases there is a linear relationship between temperature and pressure (see gas laws ), i.e., gase... Read more
Nicolas Léonard Sadi Carnot
Nicolas Léonard Sadi Carnot , 1796-1832, French physicist, a founder of modern thermodynamics; son of Lazare N. M. Carnot. His famous work on the motive power of heat ( Réflexions sur la puissance motrice du feu, 1824) is concerned with the relation between heat and mechanical energy.... Read more
black body
black body in physics, an ideal black substance that absorbs all and reflects none of the radiant energy falling on it. Lampblack, or powdered carbon, which reflects less than 2% of the radiation falling on it, crudely approximates an ideal black body; a material consisting of a carpetlike arrangem... Read more
expansion
expansion in physics, increase in volume resulting from an increase in temperature. Contraction is the reverse process. When heat is applied to a body, the rate of vibration and the distances between the molecules composing it are increased and, hence, the space occupied by the body, i.e., its volu... Read more
