The vacuum refers to a space devoid of matter or substance, characterized by the absence of air and other gases.In physics, a perfect vacuum contains no particles, and its pressure is zero.
While achieving a complete vacuum is challenging, partial vacuums are commonly used in various technological applications like vacuum tubes and vacuum chambers.
In cosmology, the vacuum of space is not entirely empty, containing low-density particles and energy. Understanding vacuums is essential in physics and engineering, influencing technologies ranging from vacuum cleaners to advanced scientific instruments.
