This absolute scale is known today as the kelvin thermodynamic temperature scale. The most widely used absolute temperature scale is the kelvin.
The absolute or thermodynamic kelvin, temperature scale temperature is a measure of the hotness of something. It is reasonable to expect that the lowest temperature possible is one where all of this motion either ceases or becomes as small as possible. Kelvin is also used for pinpointing color temperature. Kelvin scale are the absolute zero of temperature, which is assigned the temperature 0 k, and the triple point of the watericesteam. Fast, computer supported experimental determination of absolute. The kelvin scale and the rankine scale are absolute temperature scales. The three common temperature scales are celsius, fahrenheit, and kelvin.
Each scale has its uses, so its likely youll encounter them and need to convert between them. Another absolute temperature scale, the rankine temperature scale, is used in some engineering applications. A scale for absolute temperature with degree units the. Absolute temperature, also called thermodynamic temperature, is the temperature of an object on a scale where 0 is taken as absolute zero.
