Absolute Zero's Applications?
544408
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

Zero (0) is a paradoxical number that has high philosophical and scientific importance. Context of zero in absolute & applied Mathematics is different. In applied mathematics we use it according to our convenience, for example 0 degree celsius, 0!(factorial), initial Velocity, initial position etc. And in Absolute Mathematics we think of it transcendently. Absolute zero is beyond our experience.Therefore we are using and thinking of zero in diffrent context. \nIn the fraction a/o, at present the numerator `a' is considered as something that is considerable. And the denominator `0' is not used in the absolute sense insted it  is taken in the concept of `infinitesimally small'.That is the symbol `0' here stands for `infinatesimally small'.For instance a `point' is considered as magnitude and dimensionless which is relatively true and wrong in the absolute sense.\nContext a/0=a is also correct iff same meanig is strected all through. ie. a/0 implies `a' is `undivided'.Then a*0 means a is not at all multiplied, hence a*0=a only in the absolute sense. Here `a' which is the quotient and  the product is same to both expressions implies that `a' is individual and Independent.This concept is non-pragmatic hence not in use.\nMathematically,a=(1+1+1...`a' times).\nGeneraly, if a/m =n, a=m*n = (m+m+m+...`n' times) \nAnd, if m is infinatesimally small,a=(m+m+m+... infinite  times).At present the parodoxical symbol `0' is used to denote the axiom `infintesimaly small'.consequently. it is written as a/0= `Infinity'\nNote that divisibility exists iff something exists in the denominator.And in the same way multiplicability exits iff something exits as multiplier.

As for me I think all is persuasive. If you start to count temperature from the point when its length = 50cm you better write: L=50*e^(kt) cm. \nNow (iii): the constant k is valid to be unchangeable in rather narrow range of temperatures, in real physics k depends on t. And after melting the whole business does not work at all. On the other hand the function L=50*e^(kt) says that if t<<0 L is expected to shrink to 0, ignoring the fact that t cant be lower than absolute 0.

Since p(x) has even degree and the leading coefficient is positive, p(x) → ±∞. Thus, there is an absolute minimum but no absolute maximum. Since if f has an absolute extremum on an open interval (a,b) , then it must occur at a critical point of f [applied to the interval (-∞, +∞)], the absolute minimum must occur at a critical point of p. Since p is differentiable everywhere, we can find all critical points by solving the equation p'(x) = 0. This equation is:\n\n12x^3 + 12x^2 = 12x^2(x+1) = 0\n\nfrom which we conclude that the critical points are x = 0 and x = -1. Evaluating p at these critical points yields:\n\np(0) = 0 and p(-1) = -1\n\nTherefore, p has an absolute minimum of -1 at x = -1

Uh...one and one-fourth degrees below zero.  (Is this a trick question?)

NOOOOOOOOOO!!!!!!!!!!\nAbsolute zero simply means that all EXCESS energy from the system will have been removed - the system will still have ground-state energy!\nThink of the quantum harmonic oscillator, E = (n+1/2)hw/2pi\nEven if n=0 (lowest energy state for the oscillator) there is still some energy.\nIf you model the vibrations of atoms as independent harmonic oscillators, you will see that all molecular motion DOES NOT STOP at absolute zero.\n\nFurthermore, whether something is solid depends not only on the temperature, but also on the pressure.\nExperiments have shown that liquid helium stays liquid until all the way to about 0.0001 kelvin (about the lowest temperature ever reached) at atmospheric pressure, (but displays superfluidity) but that increasing the pressure will cause it to solidify at some temperature.\n\nI am sorry to get so side-tracked answering this question, but i felt that the misconceptions of the other answerers must be addressed.\nIn answer to your question, no, not everything will be solid at absolute zero.

Absolute zero refers to 0 degress Kelvin -- a measure of temperature.\n\nA Joule is the "metric" standard measure of energy.\n\nCalories are an older measure of thermal energy.\n\n1 Calorie = 4.18 Joules.

Disregard butchtroll, he doesn't know anything and is obviously just guessing.\n\nA absolute zero, although practically impossible to reach, it is theoretically very easy to calculate. Just assume that all particles have a velocity of zero, and calculate the lowest potential structure according to the lennard-jones potential and possible electro-static potential. The result concludes a structure quite similar to crystals at living-room temperature.\n\nButch - practically as in cannot be obtained through anything but theoretical experiments. Although, temperatures can actually be achieved that is sufficiently low to allow, in some degree, to regard matter as having a temperature of absolute zero. Theoretically, if such matter should exist, it would affect the universe in any significant way. That the universe cease to exist if absolute zero was reached, would be a prerequisite, not a result. You can do that math yourself and see if it is possible - or borrow the particle similator program I've written.\n\nmore: I find it funny that you preach about humility, after calling me an idiot. Especially after mixing different types of energy together and calling the lot for temperature. Sure, if an atom contain absolutely no energy, it would collapse into a black hole. But temperature is NOT a measure of total energy.\n\nyet more: Still you call me an idiot, and still you attempt to call humiliary high ground. I'm not saying I know everything myself - but wheter temperature is all energy, or just momentum of "particles", is pretty far from'everything'. As a student in nanotechnology, I can honestly say that, you sir, are blinded by your own feeble knowledge of physics. Temperature of matter is usually described as the summation of vibrational, momentum, rotational energy and phonons. NOT electronic excitation or any kind of potential energy.\n\nYour question was inane, and I *did* answer it. Nothing would happen with the universe if a cloud of hydrogen would suddenly come into existence with a temperature of zero kelvin. If you don't understand what I'm writing, just say so, instead of stating that I didn't answer your question.\n\nWhat do you attempt to prove with your citation? You seem lost, sir?\n\nWhat do you need a value of? What the temperature of the solid hydrogen would be after 1 second? Sorry, but I don't care enough to calculate how much a certain amount of hydrogen crystal would increase in temperature from background radiation.

Absolute values can be very tricky so be careful with it. \nAll you need to know is that \n   *  if x<0  then |x|= -x\n   *  if x=0 then |x| = 0\n   * if x>0 then |x|=x\nIn your case, start with what's inside the absolute value.\nSo if 3-y>0 then x=3-y\nIn other words for y<3, y=3-x\nif 3-y=0, then x=0 (so for x=0 y=3)\nif 3-y<0 then x=-(3-y) = y-3\nThat is, for y>3, y=x+3\nSo you have to graph both functions y=3-x and y=x+3. When y<3 you take the first function and when y>3 you take the second one.\nFor your second function you forgot something but I'm guessing it was y=|x|. If it's the case just graph y=x (for x>0) and y=-x (for x<0). This will give you a symmetrical graph.\nIf you still have problems don't be scared to ask.\nHope this helps

absolute values are important in higher levels of analysis when using wide ranges of numbers, also it help when we try to have equations of only real numbers make sense sometimes, i.e. various sorts of root equations

Absolute zero is the temperature at which sub-atomic particles cease to move.\n\nIn Celsius, that temperature is -273 degrees, or 0 Kelvin, which is the absolute scale in the SI system.\n\nIn Fahrenheit, it is -460 degrees, or 0 Rankine, the absolute scale in the English system.\n\nThe absolute scales are used when doing computations that include temperature, because it "provides a continuous definition of temperature, valid over all ranges of temperature. The normal temperature scales are based on the temperature at which water freezes, and the interval of measurement is determined by the distance to the temperature at which water boils.\n\nTherefore, since there is no temperature below absolute zero (since temperature is fundamentally the measurement of the movement of particles), it can be used as a standardized starting point for a scale of measurement.

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.

some of these sound like biology questions and i'm a little rusty but i'll see what i can do..\n\n1. Define 'absolute you are zero' and explain why we can't get to it.\n\nabsolute zero is when everything is zero degrees. the reason we cannot reach absolute zero is because everything is touching another thing. which means heat is transferred to anything and everything, so it's impossible for everything to be zero degrees. if we were to reach absolute zero you would be able to walk through a wall because the atoms would all slide past eachother, because they wouldn't be moving because the moving makes heat. that's just an example because i'm not very good at explaining the concept, i just understand it.\n\n2. (+1)+(-78)= -77\n3. (-10)+(-5)= -15\n4. Define what homogeneous is and give me an example. \n\nhomogeneous means: homo-same. geneous-genes/traits. for example two people with brown eyes are homogeneous because they have the same trait for that eye color in their dna.\n\n5. Define what hertrogeneous is and give me an example. \n\nsame thing as above but hetero-different. like someone with brown eyes and another person with green.\n\n6. If there are 16 the winner!!! people at a party and 5 leave and it doubled for the amount of people, how much are there now? 22\n7. (-9)+(-7)= -16\n8. Who is the author of the Gaurdians of Ga'Hoole series. i don't know\n9. Who is the author of Deltora Quest. i don't know\n10. This one is a code. The code is hid in this post. ????

Zero - is it positive or negative?

another zero would be the conjugate of the one you know,\nthen try the rational zeros test, or even syn div

There is no number that will multiply by zero to not equal zero because for example 5x5 would be the quantity of five added five times, 5x1 would be the quantity of five added one time, and 5x0 would be the quantity of five added zero times meaning there is nothing there or, if you prefer, that the quantity (Five) is not addded at all.\n\nBTW- even infinity multiplied by zero equals zero\nBTW- There is NO NUMBER!!! that will multiply by zero to to equal anything but Zero. Not Infinity or undefined!! 0x0=ZERO Infinity x 0=ZERO, ETC.

at 0K, vibrational movements of atoms stop ... this means that atoms are completely stationary - in other words, they have no energy ... this state is known as absolute zero.
