Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

The temperature of absolute zero is 459.67 degrees below zero Fahrenheit, the lowest temperature possible. It is the temperature at which no molecular motion exists and it represents the total absence ...

Temperature is typically thought of as the average energy of individual atoms or molecules within a given collection. For atoms of similar mass, this "kinetic temperature" would basically be their ...

TORONTO, Ontario (CTV Network) — Scientists have broken the record for the coldest temperature ever recorded in a lab, achieving a temperature just trillionths of a degree away from absolute zero by ...

The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature – one can only approach absolute zero. This is the third law of ...

Researchers from Hanns-Christoph Nägerl's group have produced the world's first ultracold KCs molecules in their absolute ground state. Starting by mixing clouds of potassium and cesium atoms cooled ...

Physicists in Germany have produced the coldest temperature ever recorded – a chilly 38 trillionths of a degree above absolute zero. The strange experiment involved dropping a quantum gas, and ...

Energy distribution of atoms in a thermal state. For positive absolute temperatures (upper part, blue), the low energy states have the highest population; for negative absolute temperatures, the high ...
