B) Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume.

Most modern thermometers are graduated with both the Celsius temperature scale and the Fahrenheit temperature scale.

In certain fields of engineering, another absolute temperature scale, the Rankine scale (see William Rankine), is preferred over the Kelvin scale. Its unit of measure—the degree Rankine (°R)—equals the Fahrenheit degree, as the kelvin equals one Celsius degree.

The Réaumur (°Re) temperature scale (or octogesimal division) was widely used in parts of Europe in the 18th and 19th centuries; it later was used primarily to measure the temperature of mixtures during brewing, of syrups in the production of certain food products, and of milk during cheese making.
