what is absolute scale of temperature?explain in detail?

Answer 1

It's Kelvin, instead of Fahrenheit or Celsius

"Kelvin temperature scale is the base unit of thermodynamic temperature measurement in the International System (SI) of measurement. It is defined as 1/ 273.16 of the triple point (equilibrium among the solid, liquid, and gaseous phases) of pure water. The kelvin (symbol K without the degree sign []) is also the fundamental unit of the Kelvin scale, an absolute temperature scale named for the British physicist William Thomson, Baron Kelvin. Such a scale has as its zero point absolute zero, the theoretical temperature at which the molecules of a substance have the lowest energy. Many physical laws and formulas can be expressed more simply when an absolute temperature scale is used; accordingly, the Kelvin scale has been adopted as the international standard for scientific temperature measurement. The Kelvin scale is related to the Celsius scale. The difference between the freezing and boiling points of water is 100 degrees in each, so that a degree Kelvin has the same magnitude as the degree Celsius."

Absolute Scale Of Temperature

Answer 3

Absolute Temperature Scale

Answer 4

The absolute temperature scale is also called the Kelvin temperature scale, developed by Lord Kelvin.

Kelvin temperature scale,


a temperature scale having an absolute zero below which temperatures do not exist. Absolute zero, or 0°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of -273.15° on the Celsius temperature scale. The Kelvin degree is the same size as the Celsius degree; hence the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15°K and 373.15°K, respectively. When writing temperatures in the Kelvin scale, it is the convention to omit the degree symbol and merely use the letter K. The temperature scale is named after the British mathematician and physicist William Thomson Kelvin, who proposed it in 1848.

This scale was developed to do calculations with gases. If the Celcius or Fahrenheit temperature scales were used in these calculations you would get negative volumes, which isn't possible. The lowest temperature is 0K

Answer 5

Temperature is one of those aspects of the everyday world that seems rather abstract when viewed from the standpoint of physics. In scientific terms, it is not simply a measure of hot and cold, but an indicator of molecular motion and energy flow. Thermometers measure temperature by a number of means, including the expansion that takes place in a medium such as mercury or alcohol. These measuring devices are gauged in several different ways, with scales based on the freezing and boiling points of water—as well as, in the case of the absolute temperature scale, the point at which all molecular motion virtually ceases.

Answer 6

In absolute scale, temperature is measured in Kelvin(not degree Kelvin).

The zero of Absolute scale coincides with -273 of Celsius scale and zero of Celsius coincides with 273 of Absolute scale.

Answer 7

Absolute degrees, or Kelvin degrees, are the same size as Celsius degrees(i.e. a 1 degree increase in Kelvin is the same as a 1 degree increase in Celsius.) But whereas Celsius starts at the temperature that water freezes at, 0 degree Kelvin is the temperature at which there is no energy whatsoever--no heat, not even any molecular movement, nothing. This theoretical point is called absolute zero, and it is impossible for anything to be colder than, or even equal to absolute zero.

Absolute zero is –273.15 °C on the Celsius scale and –459.67 °F on the Fahrenheit scale.

Answer 8

absolute temperature scale
A temperature scale based upon the value zero as the lowest possible value. Thus, all obtainable temperatures are positive. The Kelvin and Rankine scales are absolute scales.

Answer 9

Kelvin is the absolute temperature scale. At 0 degrees Kelvin, there is no molecular movement. This temperature has never been acheived, but has been nearly reached. Kelvin can convert to other temperatures scale very easily.

Answer 10

In an absolute temperature scale 0 degrees in the temperature at which all molecular motion stops - ie the coldest possible temperature.
