is it possible to achieve a temperature below absolute zero?why?thanks!:)?

Answer 1

No. And here's the reasoning:
Temperature is a measure of the average amount of the molecular motion in an object. Temperature decreases as the amount of molecular motion decreases.
Absolute zero is - by definition - the point where there is zero molecular motion in an object: everything is completely stopped.
Since there is no way to stop something MORE when it's already completely stopped, there's no way to reduce the temperature lower than absolute zero.

Answer 2

Tempreature Energy is relative and is measured in degrees.
The graduation of temperature energy radiation is made relative to a reference point. That reference point is the Zero degree absolute. It was coined by Sir W. thomson(lord Kelvin)
It is a point where a Gas has theoretically zero volume.Of course a gas changes phase and becomes a liquid before it can reach zero degrees absolute(0 K).
What happens At Zero degree absolute is as the temperature energy is completely removed from between the atoms,theorethically there is no more heat pressure existing trying to push the atoms apart against the electrostatic gravity field. Hence the atoms are pushed together to a limit. So they are all snug against each other and have no space to compress any further. They are kept apart only because a reverse gravity field (Gravitational repulsion Phenomenon)is created due the the high compression of the substance of space that exists between the atoms at that limit.
Therefore; it is impossible to remove any more temperature energy without removing Energy from the inside of the atom itself. It would take a tremendous amount of power to do that ,and the result would be a severe chalenge to the structure of the atom.

Therefore aboslute zero is not possible to achieve.However lab experiments have come very close to it by freezing Helium gas.

Answer 3

No, sorry ;-)

Basically, what we call "temperature", is just a measure, at our (large) scale, of how agitated the atoms or molecules are, in a substance.

You may know that atoms or molecules constantly vibrate around their position of equilibrium.

So temperature is a measure of how much (thermal) energy there is inside a substance. The more there is, the more things vibrate around their positions. If you get them to vibrate enough, then, say, a solid becomes a liquid. Or a liquid becomes a gas.


So now what is the "absolute zero"? It is a state where there is no more thermal energy left, and as a consequence, the atoms and molecules stop vibrating. So, yes, every substance is a solid, even hydrogen (H freezes at -434.5F = -259.1C, and is metallic).


So can you go below a temperature where there is no more energy? No.


Hope this helps

Answer 4

Not in any conventional sense. Temperature measures the average motion of molecules. When the temperature is at absolute zero, this motion all stops (more technically, it is as small as possible). Since you can't have less motion than none, absolute zero is as cold as you can go.

With this said, it IS possible to make sense of negative temperatures in certain very specific situations, but the concept of temperature used then is a bit different than the usual 'amount of motion' above. Here, the temperature is related to how energy is distributed in your material. In certain magnetic materials, the distribution is opposite the usual one, so these materials can be thought of as having negative temperatures. However, these negative temperatures are actually hotter than absolute zero. Wierd huh?

Answer 5

No you can't go below absolute zero. The reason being, is you remove all the energy from the particles, and they stop moving. The only way you could then remove more energy from them, is to remove mass (following the laws of e=mc^2), however this would not result in a reduction in temperature, only in mass.

So absolute zero is the coldest temperature you can get to -273.15degrees c, or 0 kelvin.

Oh, by the way, no one has managed a temperature below absolute zero as yet, only close to it.

Answer 6

Heat flows from hot to cold and there is nothing colder than absolute zero to draw heat away from the object you wish to cool. You can remove potential energy (of elevation) from an object by lowering it but it can not go below the physical floor and must stop. Einstein showed that E = m(c squared) and there is still 'energy' left in the mass of an object at absolute zero but no practical means to unlock and drain it. Uranium at absolute zero can still fission producing energy but that energy can not be drained away until it elevates the fission products above the absolute zero floor. At absolute zero, atoms and molecules are at minimum vibratory energy and electrons are in rest orbits that can not produce (infrared) heat photons. Of course producing and maintaining absolute zero is next to impossible but may be achieved for a cluster of atoms or molecules (until a penetrating cosmic ray adds energy?). Think of absolute zero as the point where all the cars in a parking lot have run out of gas and their batteries are dead too. They have no energy left to give (unless you somehow burn them in a nuclear reactor?).

Answer 7

Technically, yes. Normally, the number of accessible quantum states of a system increases rapidly with energy. That's the reason temperature usually increases with energy. Without going into definitions (look it up), if, however, the number of quantum states beyond a given system energy starts to decrease again at some point, it can be said to have a negative temperature. Spin states do this.

Answer 8

0 Kelvin is "absolute 0" the component at which all atomic action ceases. this suggests all electrons are in the backside a danger skill state and there isn't any measurable kinetic skill. considering that Temperature is a level of atomic or molecular kinetic skill it isn't any longer a danger to circulate adverse in this scale. Te 0.33 regulation of thermodynamics states that certainly the 0 of temperature won't be able to be attained by utilising any finite style of steps (The entropy of all suited crystalline solids is 0 at absolute 0 temperature).

Answer 9

Absolute zero is a reference to all known molecules to stop 'moving'. Even the molecules carrying the cold energy stops working.

Answer 10

Because the molecules can not rule die at absolute zero
good luck
