Question

What is the absolute temperature? How is it defined?

Answer 1

Absolute temperature , also called thermodynamic temperature , is the temperature of an object on a scale where 0 is taken as absolute zero . Absolute temperature scales are Kelvin ( degree units Celsius ) and Rankine ( degree units Fahrenheit ).

Absolute zero is the temperature at which a system is in the state of lowest possible (minimum) energy. As molecules approach this temperature their movements drop towards zero. It is the lowest temperature a gas thermometer can measure. No electronic devices work at this temperature.The Kinetic Energy of the molecules becomes negotiable or zero.
