What Is a Vacuum in Science? Definition and Examples
WEBApr 12, 2021 · In science, a vacuum is a volume that contains little or no matter. In other words, a vacuum is a region with an extremely low pressure . The word “vacuum” comes from the Latin word vacuus , meaning “empty.”
Vacuum - Wikipedia
WEBA vacuum (pl.: vacuums or vacua) is space devoid of matter. The word is derived from the Latin adjective vacuus (neuter vacuum) meaning "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. [1]
Vacuum | Definition & Facts | Britannica
WEBVacuum, space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there. It is a condition well below normal atmospheric pressure and is measured in units of pressure (the pascal).
WEBVacuum physics is the necessary condition for scientific research and modern high technology. In this introduction to the physics and technology of vacuum the basic concepts of a gas composed of atoms and molecules are presented. These gas particles are contained in a partially empty volume forming the vacuum.
