1. : emptiness of space. 2. a. : a space absolutely devoid of matter. b. : a space partially exhausted (as to the highest degree possible) by artificial means (such as an air pump) c. : a degree of rarefaction below atmospheric pressure. 3. a. : a state or condition resembling a vacuum : void.
A 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]
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, 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).
VACUUM definition: 1. a space from which most or all of the matter has been removed, or where there is little or no…. Learn more.
A region of space having extremely low gas pressure relative to surrounding pressure. The air pump of a vacuum cleaner, for example, drastically reduces the air pressure inside the device, creating a vacuum; the pressure difference causes air to rush into it, carrying dust and debris along with it. vacuum. The absence of matter.
A vacuum is essentially a great lack of something — a place where virtually all matter, even air, has been removed. It can describe something that's literally empty — or something that just seems that way, like a political vacuum.
An enclosed space, such as the space inside a container, in which there are far fewer gas molecules than in an equal volume of the air outside it. A vacuum has a much lower gas pressure than that of the atmosphere at sea level.
VACUUM meaning: 1 : an empty space in which there is no air or other gas a space from which all or most of the air has been removed; 2 : vacuum cleaner
VACUUM meaning: 1. a space that has no air or other gas in it 2. a situation in which someone or something…. Learn more.
