空氣可以被壓縮的極限是...？

The critical temperature (臨界溫度) for air is -141 degree Celsius. That is to say, at room temperature (23 degrees Celsius), air can be compressed indefinitely without being turned into liquid.

However, if the air temperature is lowered to the critical temperature ( -141 degrees Celsius), a pressure greater than 38 atmospheric pressure (critical pressure 臨界壓力) turns the air into liquid. The density of air at such temperature and pressure is about 100 kg/m^2.

sorry... a typo in the unit for density. It should be 100 kg/m^3.

我想理論上是可以的,但空氣是因溫度高低而轉變,高溫密度就大,低溫密度就少,
但有無方法可做到絕對零度呢﹖在現在科學仍未做到。

不是空氣極限，是容器的極限。
