Wat happens if we can obtain more than absolute zero temperature?

Question

wat will be the condition and will objects follow the laws of physics,then?

Answer 1

Well, if u achieve that temperature viz.lower than 0K, theoretically volume will be negative.Even when u approach that temperature, the 5th state of matter comes up which is an undistinguishable mass of atoms. Also, here Charle's etcs laws will fail since pressure cannot be negative. One another thing will happen when u reach 0K-all fundamental particles will have 0 K.E. i.e.they won't even vibrate.

Answer 2

I take it you mean a temperature lower than absolute zero. By definition, there is no such temperature.

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 molecules do not move (relative to the rest of the body) more than they are required to by a quantum mechanical effect called zero-point energy. It is a theoretical limit and cannot be achieved although it has been closely approached..

By international agreement, absolute zero is defined as precisely 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale, and −273.15 °C on the Celsius (centigrade) scale.[1] Absolute zero is also precisely equivalent to 0 °R on the Rankine scale (also a thermodynamic temperature scale), and −459.67 °F on the Fahrenheit scale. Though it is not possible to cool any substance to 0 K,[2] scientists have made great advancements in achieving temperatures close to absolute zero, where matter exhibits quantum effects such as superconductivity and superfluidity. In 2000 the Helsinki University of Technology reported reaching temperatures of 100 pK (1×10−10K).

That's cold enough for most people and weird things happen down there (quantum effects)

Answer 3

The condition will be a substance at a temperature of greater than −273.15 °C

There will remain heat energy in the substance, and the law of physics will be obeyed, as always.

Or are you asking if we can cool something to less than 0K? We can't even get it to that, but I suppose if we did cool something down to -1K, then the only result I can see is scientists are wrong about the nature of thermal energy.  

Answer 4

I assume you mean less than absolute zero, as we have always had more.  Absolute zero is only theoretical, and has never been achieved.  At absolute zero, all molecules freeze, and the very atoms would become just a pile of electrons and protons.

Answer 5

Why do we constantly get these questions: what happens if we exceed the speed of light? This question which actually asks the opposite of what is written, what happens if we can get a temperature less than absolute zero? If any of these conditions are met, we would have to completely and radically change the whole basis of our scientific thinking. There are certain things which we have to accept. Now I am going to ask my own question just to show how ridiculous these questions are: My question: if I could reduce my age to less than the age at which I was born, would I be traveling back in time ? Ridiculous isn't it ?

Answer 6

Absolute zero is impossible to reach, and below that temperature is also impossible.

Like the speed of light. Can't reach it, can't go beyond it.

And questions about conditions beyond these limits are meaningless.

.

Answer 7

Impossible. All atomic motion ceases.

Answer 8

Nothing can be colder than absolute zero. Be we DO reach thremodynamic temperatures that are negative on the Kelvin scale all the time. This is because thermodynamic temperature is negative in systems in which allowed energy states are populated in a particular way.

As an example, the semicondutor laser in your CD player operates with states at negative absolute temperature.
