What is absolute zero in temperature?
598817
Absolute zero is the zero point of the ideal gas temperature scale, denoted by 0 degrees on the Kelvin and Rankine temperature scales, which is equivalent to −273.15°C and −459.67°F.\n\nFor most gases there is a linear relationship between temperature and pressure i.e., gases contract indefinitely as the temperature is decreased. Theoretically, at absolute zero the volume of an ideal gas would be zero and all molecular motion would cease. In actuality, all gases condense to solids or liquids well above this point. Although absolute zero cannot be reached, temperatures within a few billionths of a degree above absolute zero have been achieved in the laboratory. At such low temperatures, gases assume nontraditional states, the Bose-Einstein and fermionic condensates.

theoretically, at any temperature above absolute zero, a reaction can occur.  There are very few reactions that are likely to take place at that temperature, but none that are impossible.

i never really thought about it and so i was just going to say that temperature doesnt matter because its a vacuum and is dealing with the pressure... but when i thought about it... come to think of it, i do have an answer for you.  the temperature would be zero kelvin, absolute zero.\n\n in an absolute vacuum, the pressure would be 0 if there were no particles, because the more particles you cram into one place, the more pressure there is because p=F/A pressure equals the force of the particles divided by the area of the wall of the container, so with no force of particles(since there are no partiles), the pressure would be zero.  in an absolute vacuum, there are no particles.  Now, if the pressure is zero, then according to the formula PV=nRT (which is just the ideal gas law formula,) if P(pressure) equals 0, i think that means that T(temperature in Kelvin)would also be 0 which would mean that the temperature would be at absolute zero(which is defined as the temperature where all matter stops moving.. not that this would make a difference because there are no particles there because it's an absolute vacuum.  \n\nThis is what i suspect and to confirm my beliefs,  it is consistent with the fact that someone else said that outer space was 3K, and although it's very close to an absolute vacuum, there are a few particles and atoms of gas floating around there, and so it is not quite an absolute vacuum, and the temperature is 3K, meaning it's not quite at absolute zero.  so it stands to reason that since temperature decreases when pressure decreases, that in an absolute vacuum the temperature would be absolute zero, 0 kelvin.\n\ni hope this is a "good answer" and that i made sense while i took you through my reasoning :)

If you mean absolute zero, a quick look in the Handbook shows tungsten with a transition temperature of .0154 degrees Kelvin.\n\nMore people care about high temperature superconductivity, since we receive the benefits with less cooling expense.  The highest I have from 1994 is 128 degrees K, Tl2Ba2Ca2Cu3O10.  Most are ceramics of tellurium and bismuth.

Absolute zero is a fundamental lower bound on the temperature of any macroscopic system. It is approximately -273.15 degrees Celsius. It is unachievable in practice but it exists as a limit for real physical phenomena, and it was inferred by extrapolation from kinetic theory, and from other considerations in theoretical physics. One would like to define it as the temperature at which all motion ceases, but even at absolute zero some motion remains due to the requirements of quantum mechanics. Alternate definitions are that absolute zero is the temperature at which no further energy can be extracted from a physical body, or the temperature at which the entropies of perfect crystals vanish, or the temperature at which the entropy change of an adiabatic process vanishes.\n\nA state of absolute zero was first proposed by Guillaume Amontons in 1702 who was investigating the relationship between pressure and temperature in gases. He lacked accurate and precise thermometers so his results were only semi-quantitative, but he established that the pressure of a gas increases by roughly one-third between "cold" temperatures and the boiling point of water. His work led him to speculate that a sufficient reduction in temperature would lead to the disappearance of pressure. The problem is that all real gases liquefy during the approach to absolute zero.\n\nIn 1848, William Thomson, 1st Baron Kelvin proposed an absolute thermodynamic temperature scale in which equal reduction in measured temperature gave rise to equal reduction in the heat of a body. This freed the concept from the constraints of the gas laws and established absolute zero as the temperature at which no further heat could be removed from a body. Absolute zero has never been reached, and it appears it never will be. It may be asymptotically approached like the speed of light, but never attained.\n\nKinetic theory and motion\nAccording to kinetic theory, there should be no movement of individual molecules at absolute zero, so any material at this temperature would be solid. In a monatomic gas, most of the energy is in the form of translational motion, and the temperature can be measured in terms of the distribution of this motion, with slower speeds corresponding to lower temperatures, perhaps even down to absolute zero. But this is contrary to experimental evidence, and it is predicted that helium will never solidify, no matter how much it is cooled or compressed.\n\nBecause of quantum-mechanical effects, the speed at absolute zero is larger than zero and depends, along with the energy, on the volume within which a particle is confined. At absolute zero, the molecules and atoms in a system are all in their ground state, the state of lowest possible energy, and a system has the least amount of kinetic energy allowed by the laws of physics. But the lowest possible zero-point energy for a confined particle in a box is not zero. Rather than being fixed and non-moving, the equation for the energy levels shows that no matter how low the temperature gets, even when the quantum number takes its minimum value of one, a particle still has some translational kinetic energy and motion. This is a reflection of Heisenberg's uncertainty principle, which states that the position and the momentum of a particle cannot both be known precisely at any given time.\n\nSimilarly, using the harmonic approximation for the vibrations of a diatomic molecule, the quantum harmonic oscillator yields a positive zero-point energy even when the vibrational quantum number takes its minimum value of zero. For polyatomic molecules, and for bodies such as crystals, whose normal mode motions can not be assigned to individual atoms or chemical bonds, the lowest-energy state is that of the system as a whole.\n\nClassically, the absolute temperature T of a system of molecules at thermodynamic equilibrium assigns an average of 1/2 kT to each quadratic kinetic and/or potential energy term in each mechanica

The concept of absolute zero temperature is of greatest use in calculating the entropy of a system.Normally, not entropy but only the change in entropy can be calculated for a given system.But as per classical Kinetic Theory of Gases, molecular motion stops at absolute zero.Hence the entropy of a solid crystal structure is zero at absolute zero.So the difference in entropy for a system at a given temperature and that at absolute zero is the entropy of the system at given temperature itself.Hence it is difficult to obtain temperature very close to absolute zero(never absolute zero) but using modern technology it is possible and hence there can be just marginal error in the calculation of entropy of a system at a given temperature

100 degrees Fahrenheit was originally defined to be the average internal temperature of a cow (since cows were easily accessible when the Fahrenheit scale was being developed).  0 degrees was defined as the temperature of an ammonium nitrate solution (people used ammonium nitrate back then as a form of refrigeration).  1 degree Fahrenheit is equal to 1/100th of that temperature difference.

Well considering temperature is just a measure of the speed of the particles moving in a substance, the lowest temperature would be where there is no motion in the particles of a substance. This is called absolute zero which is measured as −459.67°F. This has never been acheived by scientists but they have come to within several thousanths of a degree away from it.

Considering you said 0 degrees without specifying Fahrenheit or Celcius, it seems you don't know much about science.  If the compounds are "no longer active on the molecular level" you're talking about 0 Kelvins, which are not degrees.  There's no such thing as zero degrees Kelvin.  I don't see why you're convinced that electricity would make any difference.  Put simply, the answer to your question is currently No.  Maybe someday we can have some sort of hibernation, but it will probably include hormones or something, not just zapping you.

Assuming that you mean the triplet state of oxygen, it's zero. The heat of formation of the naturally occuring ground state of an element is zero.

Anyone thinking that hasn't spent any time at my place.\n\nAbsolute Zero is how cold it is when hydrogen atoms stop moving.\n\nAnything colder than that is the area in and around my bed immediately after I ask my wife for sex.

zero, that number which, when added to any number, leaves the latter unchanged; its symbol is 0. The introduction of zero into the decimal system was the most significant achievement in the development of a number system in which calculation with large numbers was feasible. Without it, modern astronomy, physics, and chemistry would have been unthinkable as we know them. The lack of such a symbol was one of the serious drawbacks of Greek mathematics. Its existence in the West is probably due to the Arabs, who, having obtained it from the Hindus, passed it on to European mathematicians in the latter part of the Middle Ages. The Maya of Central America and probably the Babylonians also invented zero. With the extension of the number system to negative as well as positive numbers, zero became the name for that position on the scale of integers between −1 and +1. It is used in this sense in speaking of zero degrees on the Fahrenheit and Celsius temperature scales; “absolute zero” is a term used by physicists and chemists to indicate the theoretically lowest possible temperature—a use reminiscent of zero as a symbol for nothing. Unlike other numbers, zero has certain special properties in connection with the four fundamental operations. By definition zero added to or subtracted from any number leaves the number unchanged. Any number multiplied by zero gives zero. Zero multiplied by or divided by any number (other than zero) is still zero. But division by zero is undefined; i.e., there is no number that is the value of a number divided by zero.
