Absolute zero - Wikipedia, the free encyclopedia
Absolute zero is a temperature marked by a 0 entropy configuration. It is the coldest temperature theoretically possible and cannot be reached by artificial or natural means, because it is impossible...

In all of the descriptions of atomic/molecular behavior the absolute temperature enters in as 1/T^n where n>0. This reciprocal dependence always "blows up" as T approaches zero. Just "achieving absolute zero" even if it were possible would not "do much" that does not happen at 10^-6 Kelvin -- that is weird enough.

While scientists can not fully achieve a state of “zero” heat energy in a substance, they have made great advancements in achieving temperatures ever closer to absolute zero (where matter exhibits odd quantum effects).

According to Malcolm, "achieving BEC here at Sussex is going to do for atoms what lasers did for light." ... Absolute zero is reached firstly by pre-cooling atoms through bouncing lasers off them. The atoms, which are held in a high quality vacuum, like a sophisticated thermos, are then trapped with a strong magnet so that...

Though it is not theoretically 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.

Q.: How are temperatures close to absolute zero achieved and measured? ... First, let me introduce what the scientific meaning of  temperature is.:  It is a measure of the energy content of matter.  When air is hot, the molecules move fast, they have high kinetic energy.  The colder the molecules are, the smaller is...

What will happen to the gas at absolute zero temperature (0 K)? Asked by: Rohit; Answer; First of all, the gas will no longer be a gas at absolute zero, but rather a solid. As the gas is cooled, it will make a phase transition from gas into liquid, and upon further cooling from liquid to solid (ie.

Hence if C is constant, then this tends to infinity as T tends to 0, implying that it would take an infinite amount of energy to cool a sample down to absolute zero - an unattainable limit...
