State of vacuum

The state of vacuum refers to a space that is drastically empty of matter, like air or gases. In a perfect vacuum, there are no particles whatsoever. However, in practical terms, most vacuums contain very few particles and have low pressure. This state minimizes interactions with particles, making it useful for scientific experiments and precise machinery. The strength of a vacuum is often measured by how much it reduces pressure compared to normal atmospheric pressure. Essentially, a vacuum is an environment with significantly fewer particles than the air we breathe, creating an "empty" space that behaves differently than our usual surroundings.
