Question

In Absolute scale, temperature is expressed in?

Answer 1

Thermodynamic temperature is a measure of absolute temperature and one of thermodynamics' main parameters. The fundamental physical feature that imbues matter with a temperature, transferred kinetic energy due to atomic motion, begins with a thermodynamic temperature reading of zero. The Kelvin scale is used in science to quantify thermodynamic temperature, and the kelvin is the unit of measurement (unit symbol: K).

Complete step-by-step solution:
Temperature is measured in Kelvin on the absolute scale. Absolute temperature scales, with $- 273.15{\text{ }}^\circ C$ as zero and $373.15{\text{ }}^\circ C$as $100{\text{ }}^\circ C,$are known as absolute temperature scales, while -$273.15{\text{ }}^\circ C$ is known as absolute zero.
The component constituents of matter have limited motion and can't go any colder than absolute zero, the zero point of thermodynamic temperature. Absolute zero, or zero kelvin $\left( {0{\text{ }}K} \right),$is precisely equivalent to $- 273.15$degrees Celsius and $- 459.67$ degrees Fahrenheit. At absolute zero, matter has no more transferable average kinetic energy, and the only surviving particle motion is due to zero-point energy, a ubiquitous quantum mechanical phenomenon. Though the atoms in a container of liquid helium kept jostling slightly due to zero-point energy, a theoretically perfect heat engine with such helium as one of its working fluids could never transfer any net kinetic energy (heat energy) to the other working fluid and no thermodynamic work could be done.

Note: When studying the interrelationships of temperature with other physical properties of matter, such as volume or pressure (see Gay-law), Lussac's or the wavelength of its emitted black-body radiation, temperature is usually stated in absolute terms.
