Absolute Temperature -

In practice, reaching absolute zero is considered impossible (the Third Law of Thermodynamics). However, scientists have come incredibly close—within billionths of a degree. At these "ultracold" temperatures, matter begins to behave strangely, forming states like , where atoms lose their individual identity and act as a single "super-atom."

Absolute temperature is the scale of thermal measurement that starts at the lowest theoretical point possible: . absolute temperature

) is the point where that thermal motion reaches its quantum mechanical minimum. You can't get colder than absolute zero because you cannot have "less than zero" kinetic energy. 2. The Kelvin Scale In practice, reaching absolute zero is considered impossible
