Celsius is the obvious temperature scale of choice when conducting scientific experiments. Water freezes at 0. It boils at 100. It is beautiful and simple and has a lot going for it, not least of ...

For decades, a family of crystals has stumped physicists with its baffling ability to superconduct—that is, carry an electric current without any resistance—at far warmer temperatures than other ...

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 ...

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 ...

According to the third law of thermodynamics, the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 kelvin). When you purchase through links on our ...
