If an object was cooled to Absolute zero and the temperature drops, is it warmer or colder.?
605145
no...it cant get colder than absolute zero....thats why its called absolute....molecules dont move forward or backward ....you should think of them as energy particles....electrons dont really move around a nucleus either....dont think of them as planets around the sun they are more like energy fields.  the more negative the charge the more "electrons"....if there is any movement....even if it were possible to move backwards it would be warmer....movement causes friction and, therefore, heat.  it you cant get less than nothing.

The cold is less heat\n& since the heat is energy so cold is also an Energy

1. Someone said heat rises - not true. Warm air is lighter than cold air, so warm air rises. The evaporator of the fridge being on top will give a more even 'cold' distribution. If the evaporator was on the bottom, the bottom of the fridge would always be colder than the top.\n2. Cold air is heavier than warm air. If the freezer is open on top, the cold air will not escape. If the freezer is upright, with no doors, the freezer will lose all of it's 'cold' air, it will spill out of the freezer.\n3. Radiation\n4. Pit vipers have an infrared sensor. It picks up the heat generated by the rat's body heat, in the form of radiation.\n5. speed of light.

If it's non heated, it's going to be the temperature of the surrounding air and ground.

If the air cools to truly frigid Arctic temperatures such as -40 C and below then the moisture capacity of the air will be so low that likely not much snow can occur. Only at these extremely low temperatures is the phrase "it is too cold to snow" fairly valid.\n\nAt the temperature of absolute zero ( 0 K, -273 C, -459 F) all air including water vapor condenses and loses all molecular energy. The temperature can not cool below absolute zero. \n\nIts can't snow in deep space.......

The phrase "twice as cold", has no meaning.\nYou could argue that one temperature is twice as warm as another, if they were measured from absolute zero.

No. Absolute Zero is 459 degrees below zero Fahrenheit. \n\nTemperature is dependent on the rate of oscillation in molecules. At Absolute Zero the oscillations are as low as they can get.

Hot and cold are relative words we use to describe heat sensations.  As such they can not form true ratios.  Is laughter twice as good as sadness?  But in the lab, temperatures must be compared in ratios, such as to solve the perfect gas equation, and absolute temperature must be used.  For example your friend lives 100 miles from Chicago and you live 10 miles beyound that.  If you walk ten more miles farther away from Chicago are you now twice as far away as you were?  NO!  Using absolute values you must walk 110 miles farther away.\n\nFor temperatures, Absolute zero is -273K (minus 273 Kelvin degrees).  That is the temperature at which all thermal energy has been lost for all matter.  (It is like Chicago in our simple example).  Therefore, O Celcius is plus 273K and twice as cold (or half as hot) would be 136.5K or minus 136.5C, which is indeed very cold.  Brrrrr!

It depends what you mean by "twice as cold".  Without any further direction given, I would probably move to an absolute scale (Kelvin, in this case), and cut it in half.  The reason for this is that 0 Kelvin is "absolute zero", where there is no heat at all.\n\nK = C + 273\n\nThis would give:\n\n0C = 273K\n\n273K/2 = 136.5K\n\n136.5K = -136.5C\n\nSo I would say -136.5 degrees centigrade.\n\nTo be honest, I've never heard of weather getting that cold before...

Well, if it is zero degrees today, then it is 32 degrees Fahrenheit\ntoday. Since it is twice as cold tomorrow, it will be 16 degrees Fahrenheit tomorrow.

in theory, when the temp reaches absolute zero everything freezes and is -459.67 degrees F.  temps within a few billionths of a degree have been reached but the materials used in the experiment took on nontraditional states.  at the temp all molecular motion would cease so it would be impossible to reach the temp exactly.

Hot or cold is relative to your body temperature. Something less will feel blah, cool, or cold depending on how much less. Vice versa for hot. The 'starting point' for hot or cold can be different for each person, or even for the same person, like if you just worked out, everything will seem a little warmer for a while.

It's absolute zero, where there is no heat, and therefore no movement of particles.  It is -273 C.

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 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 simple answer is that it has zero temperature coefficient.

One answer would be to convert 0C into 273 Kelvin or 32 F and then do some multiplication.\n\nBut "cold" is really a subjective measure based on physiology. I suspect if you did a test with actual humans you would find that around -10.6 C feels twice as cold as 0 C.\n\nThat is what this wind chill calculator finds, if wind speed is always zero.
