WebMay 31, 2013 · Absolute zero is the temperature at which all of an object's atoms have been brought to a dead stop relative to each other. This temperature is denoted by the number zero on absolute temperature scales such as Kelvin. Absolute zero is more of a fundamental limit than a reachable temperature. WebWe call that absolute zero, measured as -273.15 °C (-459.67 °F). Scientists have yet to reach that limit in any experiment, but they're getting close. A team of physicists in Germany has...

Even space has a … WebHer personal best is a few millionths of a degree F above absolute zero, close to Ketterle's, which she, too, reached while creating BECs. "We make BECs every day now," she says …
WebNow, if you let an object perform work, it's entropy will at best stay the same, while at absolute zero it is zero. So, you can't reach absolute zero this way either. Now, we can still reach absolute zero by simply putting a system in its quantum mechanical ground state. This requires having full control of all the degrees of freedom of the system. Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion. The theoretical temperature is determined by extrapo…
