Absolute zero is the coldest point on the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value. The fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy -induced particle motion.

绝对零度（英文：The Absolute Zero），是热力学的最低温度，热力学温标的单位是K（开尔文），绝对零度就是0K（约为-273.15℃或-459.67℉）。 在此温度下，物体分子没有动能，但仍然存在势能，此时内能为最小值。

2020年8月10日 · Absolute zero is 0 K, -273.15 °C, or -459.67 °F. Absolute zero is defined as the temperature at which a cooled ideal gas is in its lowest energy state. In other words, it’s the point at which no more heat can be removed.

絕對零度（英語： absolute zero ）是熱力學的最低溫度，是粒子動能低到量子力學最低點時物質的温度，絕對零度是僅存於理論的下限值，其熱力學溫標寫成0K，等於攝氏溫標零下273.15度（即−273.15℃）或華氏溫標零下459.67度（即−459.67℉）。

2025年1月30日 · absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale .

2019年11月27日 · Absolute zero is defined as the point where no more heat can be removed from a system, according to the absolute or thermodynamic temperature scale. This corresponds to zero Kelvin , or minus 273.15 C.

2018年11月15日 · The key to decoding absolute zero is understanding what temperature is. It’s simply a measure of how fast the atoms or molecules within a substance are moving — or, to be more precise, the ...

2024年7月12日 · Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion.

Absolute zero is the lowest temperature possible. At a temperature of absolute zero there is no motion and no heat. Absolute zero occurs at a temperature of 0 kelvin, or -273.15 degrees Celsius, or at -460 degrees Fahrenheit.
