  Absolute zero - Wikipedia, the free encyclopedia
Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance.
Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion.
As mentioned, absolute or thermodynamic temperature is conventionally measured in kelvins (Celsius-size degrees), and increasingly rarely in the Rankine scale (Fahrenheit-size degrees).

This is true only if an absolute temperature scale, on which the zero-point is the absolute zero of temperature, is used.
Absolute Temperature, a temperature expressed on a scale that takes absolute zero as its own zero point.

 absolute zero
Although it might be expected that all particle motion would stop at absolute zero, this is not in fact the case.
A strange outcome of this fact is that the closely packed electrons in a metal at absolute zero would have the same energy as an ordinary gas at 50,000°C.
Denoted by zero degrees on the Kelvin scale (0 K = -273.16°C), absolute zero is physically unattainable according to the third law of thermodynamics.

 Absolute Zero...
Modern atomic theory shows that the atoms of a solid (or a liquid in the case of helium) at absolute zero have a store of kinetic energy, called zero point energy, which may be considerable.
As a matter of fact, the zero point energy of liquid helium is so large (three times as large as the heat of vaporization) that a crystal of helium under its own vapor pressure would be unstable.
Absolute Zero simply signifies the coldest something can possibly get (which is not all the way to the point of NO motion).

 Absolute Zero
Absolute Zero is a unique blend of explosiveness, subtlety, complexity, and avant garde music, all tempered with lyrics that speak to the poor and oppressed.
Absolute Zero stands ready to challenge the assumptions of the marketplace-through breaking down barriers by using every available resource.
Absolute Zero is also a tribute to the perseverance of musicians who have followed their ideals through good times and bad, through major career setbacks and career disappointments, when less hardy souls would have called it a day.

 Reaching Absolute Zero
Getting to absolute zero is less a matter of cooling something to 0 degrees Kelvin (-273 C or -459.6 F) than it is to designing a way to measure the temperature once you get there.
A consequence of the laws of thermodynamics is that it requires an infinite amount of work to attain absolute zero.
Now it is possible to achieve "temperatures" extremely close to absolute zero milli- even micro- degrees (provided that the temperature scale is properly established at those temperatures, which is by no means a trivial problem all by itself).

The temperature scale (measured from 0 K) is shown on a logarithmic scale, with T increasing by factors of 10, so that absolute zero itself is not shown.
The frequency of this electromagnetic radiation is proportional to the absolute temperature.
Near absolute zero, we can often ascribe different temperatures to various components within a single material, such as the nuclei, the conduction electrons (in a metal) and the atomic vibrations, each of which has thermal energy.

 Absolute Zero and the Conquest of Cold
Note that the definition of absolute zero is independent of the type of thermometer used.
Currently Absolute Zero is scheduled to air on PBS in the Spring of 2007.
The program is based largely on Tom Shachtman’s 1999 acclaimed book Absolute Zero and the Conquest of Cold, which is an epic story that follows a trail of eccentric characters ranging from a 17th century court magician whose alchemy brought air conditioning to Westminster Abbey to the original Captain Birdseye who invented frozen food.

 Third law of thermodynamics - Wikipedia, the free encyclopedia
The third law of thermodynamics is an axiom of nature regarding entropy and the impossibility of reaching absolute zero of temperature.
The third law of thermodynamics states that the entropy of a system at zero is a well-defined constant.
If the entropy of each element in some (perfect) crystalline state be taken as zero at the absolute zero of temperature, every substance has a finite positive entropy; but at the absolute zero of temperature the entropy may become zero, and does so become in the case of perfect crystalline substances.

 1/29/92 - What is absolute zero?   (Site not responding. Last check: 2007-10-12)
On the Fahrenheit scale, water freezes at a temperature of 32º Fahrenheit and boils at 212º F. Absolute zero on this scale is not at 0º Fahrenheit, but rather at -459º Fahrenheit.
On the Celsius scale, absolute zero corresponds to a temperature of -273º Celsius.
On this scale, water freezes at 273 K and boils at 373 K. Only on the Kelvin temperature scale does absolute zero actually fall at 0 K. The accompanying diagram compares the three temperatures scales.

Dear Cassy, The Third Law of Thermodynamics states that it is impossible for a real experimental system to be brought down to a temperature of absolute zero.

 What Does Negative Temperature Mean?   (Site not responding. Last check: 2007-10-12)
Notice that with this definition, E is zero when half of the spins are up and half are down.
So we have created a system where, as we add more and more energy, temperature starts off positive, approaches positive infinity as maximum entropy is approached, with half of all spins up.
After that, the temperature becomes negative infinite, coming down in magnitude toward zero, but always negative, as the energy increases toward maximum.
