Vacuum

What do we mean by vacuum?

Absence of matter. noun

A space empty of matter. noun

A space relatively empty of matter. noun

A space in which the pressure is significantly lower than atmospheric pressure. noun

A state of emptiness; a void. noun

A state of being sealed off from external or environmental influences; isolation. noun

A vacuum cleaner. noun

Of, relating to, or used to create a vacuum. adjective

Containing air or other gas at a reduced pressure. adjective

Operating by means of suction or by maintaining a partial vacuum. adjective

To clean with or use a vacuum cleaner. transitive & intransitive verb

Empty space; space void of matter: opposed to plenum; in practical use, an inclosed space from which the air (or other gas) has been very nearly removed, as by an air-pump. noun

A space entirely devoid of matter (called also, by way of distinction, absolute vacuum); hence, in a more general sense, a space, as the interior of a closed vessel, which has been exhausted to a high or the highest degree by an air pump or other artificial means. noun

The condition of rarefaction, or reduction of pressure below that of the atmosphere, in a vessel, as the condenser of a steam engine, which is nearly exhausted of air or steam, etc.. noun

A kind of continuous brake operated by exhausting the air from some appliance under each car, and so causing the pressure of the atmosphere to apply the brakes. noun

A kind of large closed metallic retort used in sugar making for boiling down sirup. It is so connected with an exhausting apparatus that a partial vacuum is formed within. This allows the evaporation and concentration to take place at a lower atmospheric pressure and hence also at a lower temperature, which largely obviates the danger of burning the sugar, and shortens the process. noun

Same as Pulsometer, 1. noun

Any tube used in electronic devices, containing a vacuum and used to control the flow of electrons in a circuit, as a vacuum diode, triode, tetrode, or pentode. noun

A safety valve opening inward to admit air to a vessel in which the pressure is less than that of the atmosphere, in order to prevent collapse. noun

A region of space that contains no matter.

(plural only "vacuums") A vacuum cleaner.

The condition of rarefaction, or reduction of pressure below that of the atmosphere, in a vessel, such as the condenser of a steam engine, which is nearly exhausted of air or steam, etc.

A spacetime having tensors of zero magnitude
