Definition of Absolute Zero



Absolute zero is the lowest temperature that can be attained by a substance and at this point, no heat energy is trapped by the molecules of the substance. The fundamental particles present in nature constitute no vibrational motion at the absolute zero. It has been agreed by the International committees that on the kelvin scale, 0 kelvin is the absolute zero and it is -273.16 centigrade on the Celsius scale.

 


The scientists are unable to achieve such a low temperature at which the movement of the particles is ceased, yet they have made extraordinary efforts in achieving temperature somewhat closer to absolute zero.
