1.

Base unit of thermodynamic temperature measurement in the International System of Units (SI). It is defined as 100/27,316 of the triple point (equilibrium among the solid, liquid, and gaseous phases) of pure water. The kelvin is also the fundamental unit of the Kelvin scale, an absolute temperature scale named for the British physicist William Thomson (known as Lord Kelvin). An absolute temperature scale has as its zero point absolute zero (273.15 on the Celsius temperature scale and 459.67 on the Fahrenheit temperature scale), the theoretical temperature at which the molecules of a substance have the lowest energyhence, all values on such a scale are nonnegative. Many physical laws and formulas can be expressed more simply when an absolute temperature scale is used; accordingly, the Kelvin scale has been adopted asthe international standard for scientific temperature measurement. The difference between the freezing and boiling points of water is 100 degrees in both the Kelvin and the ...more

Thermodynamic temperature is an "absolute" scale because it is the measure of the fundamental property underlying temperature: its null or zero point, absolute zero, is the temperature at which the particle constituents of matter have minimal motion and can be no colder. The absolute zero in kelvin scale is - 273 degree C .

Temperature that is measured from a base of absolute zero on the Kelvin scale or the Rankine scale. ...absolute temperature (T ) that reckoned from absolute zero (273.15C or 459.67F), expressed on an absolute scale.

Vt=v0(1+t/273),the temperature at which Vt is zero is called Absolute Temperature.
