Temperature scale in thermodynamics
Web1 Jun 2008 · The Kelvin is defined as being a unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water (273.16 K at 611.2 Pa). This scale uses the absolute zero, −273.16°C. The boiling point of water according to this scale is 373°K. The Kelvin is the SI unit of temperature. WebAbsolute zero is 0 Kelvin and -273.15 celcius. A degree celcius has the same size as a degree Kelvin. The triple point of water is 0.01 celcius. So in Kelvin the triple point of water will be 273.16 (273,15 +0.01) So 1 Kelvin can be defined as the triple point of water divided by 273,16. or 1/273.16 of the triple point of water.

WebThe thermodynamic scale or the Kelvin scale is an absolute scale of temperature that does not depend on the property of any substance , whereas the Celsius scale for instance, is … Empirical scales are based on the measurement of physical parameters that express the property of interest to be measured through some formal, most commonly a simple linear, functional relationship. For the measurement of temperature, the formal definition of thermal equilibrium in terms of the thermodynamic coordinate spaces of thermodynamic systems, expressed in the zeroth law of thermodynamics, provides the framework to measure temperature.
