When is a perfect vacuum obtained?

When is a perfect vacuum obtained? Correct Answer When both absolute pressure and molecular momentum are zero 

Explanation : 

Perfect vacuum :

  • A perfect vacuum can be defined as space with no particles of any state (solid, liquid, gas etc.).

  • It is important to note that the above definition is a theoretical understanding, although it is practically impossible to achieve perfect vacuum.

  • A perfect vacuum obtained When both absolute pressure and molecular momentum are zero.
