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 ...

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 ...

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 ...

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 ...

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 ...

IN your issue of July 25 there appeared an interesting article on the liquefaction of gases. It was shown that by rapidly evaporating hydrogen, Prof. Dewar obtained a temperature of 13–15° C.

As far as we can tell from modern science, there's no upper limit to temperature. There sure is a lower limit, though. We call that absolute zero, measured as -273.15 °C (-459.67 °F). Scientists have ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Under a tangled mess of pipes, tubes, gauges, ...
