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… 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...
