description:	Ontomatica's Temperature Data Application integrates relevant ontology rules (items, properties, relationships and constraints) with relevant data sets. The Temperature Data Application is used to specify thermal setting for preparing or consuming an ingredient, beverage or food. Background: A temperature is an objective comparative measure of hot or cold. It is measured by a thermometer, which may work through the bulk behavior of a thermometric material, detection of thermal radiation, or particle kinetic energy. Several scales and units exist for measuring temperature, the most common being Celsius (denoted °C; formerly called centigrade), Fahrenheit (denoted °F), and, especially in science, Kelvin (denoted K). The coldest theoretical temperature is absolute zero, at which the thermal motion of atoms and molecules reaches its minimum - classically, this would be a state of motionlessness, but quantum uncertainty dictates that the particles still possess a finite zero-point energy. In addition to this, a real system or object can never be brought to a temperature of absolute zero by thermodynamic means. Absolute zero is denoted as 0 K on the Kelvin scale, -273.15 °C on the Celsius scale, and -459.67 °F on the Fahrenheit scale. The kinetic theory offers a valuable but limited account of the behavior of the materials of macroscopic bodies, especially of fluids. It indicates the as proportional to the average kinetic energy of the random microscopic motions of those of their constituent microscopic particles, such as electrons, atoms, and molecules, that move freely within the material. Temperature is important in all fields of natural science, including physics, geology, chemistry, atmospheric sciences, medicine, and biology, as well as most aspects of daily life.
