Equivalently, when the entropy of a substance has been reduced to zero, the substance is at absolute zero. This is 0 on the Rankine scale and -459.67°F. Learning objectives Understand why there is an absolute zero temperature which is -273 oC. At a temperature of absolute zero there is no motion and no heat. From Simple English Wikipedia, the free encyclopedia Zero kelvin (−273.15 °C) is defined as absolute zero. This is not correct. In scientific measurement, temperature is a way of measuring atomic measure. For example, all molecular motion does not cease at absolute zero (molecules vibrate with what is called zero-point energy), but no energy from molecular motion (that is, heat energy) is available for transfer to other systems, and it is therefore correct to say that the energy at absolute zero is minimal. It is a temperature where all motions in matter stop and are considered unreachable. Absolute Zero is the scale of thermodynamic temperature when in lower limit. Cette section est vide, insuffisamment détaillée ou incomplète. At absolute zero, entropy is minimized.
