1. Absolute zero is the lowest possible temperature, at which particles have minimal energy.
绝对零度是可能的最低温度，在这个温度下，粒子的能量是最小的。

2. Scientists have never been able to reach absolute zero in a laboratory setting.
科学家们从未能在实验室环境中达到绝对零度。

3. Absolute zero is often used as a reference point for temperature scales, such as Kelvin.
绝对零度经常被用作温度标尺的参考点，比如开尔文。

4. At absolute zero, all molecular motion ceases completely.
在绝对零度下，所有分子运动完全停止。

5. Absolute zero is equivalent to -273.15 degrees Celsius or 0 Kelvin.
绝对零度相当于-273.15摄氏度或0开尔文。

6. In theory, it is impossible to reach absolute zero because it would require an infinite amount of energy.
理论上，达到绝对零度是不可能的，因为这将需要无限的能量。
