Question

Quizplus · Accepted Answer

The zero of the kelvin temperature scale corresponds to the temperature at which the motion of atoms and molecules essentially ceases, known as absolute zero. This is an important concept in thermodynamics and is a commonly used reference point for scientific measurements of temperature. The freezing point of hydrogen and the melting point of ice are used as reference points in other temperature scales, but they do not correspond to absolute zero on the Kelvin scale. The mean temperature of space is not a relevant reference point for the Kelvin scale.
