what is the correct spelling and meaning of vacuum?

Answer 1

vacuum the same

Answer 2

How Do You Spell Vacuum

Answer 3

A vacuum is a volume of space that is substansively empty of matter, so that gaseous pressure is much less than standard atmospheric pressure. The root of the word vacuum is the Latin adjective vacuus which means "empty," but space can never be perfectly empty. A perfect vacuum, known as "free space", with a gaseous pressure of absolute zero is a philosophical concept with no physical reality, not least because quantum theory predicts that no volume of space is perfectly empty in this way. Physicists often use the term "vacuum" slightly differently. They discuss ideal test results that would occur in a perfect vacuum, which they simply call "vacuum" in this context, and use the term partial vacuum to refer to the imperfect vacua realized in practice.

Your spelling is correct.

Answer 4

its spelt as vacuum...
my definition:

In physics, a vacuum is the absence of matter in a volume of space. A perfect vacuum is an ideal state that cannot really exist, but is best approximated by outer space. Physicists use the term partial vacuum to describe real-life non-ideal vacuum. A complete characterization of the physical state would require further parameters, such as temperature. The antithesis of a vacuum, which is also an ideal unachievable state, is called a plenum.
ALSO:
the absence of matter
void: an empty area or space; "the huge desert voids"; "the emptiness of outer space"; "without their support he'll be ruling in a vacuum"
a region that is devoid of matter
an electrical home appliance that cleans by suction
clean with a vacuum cleaner; "vacuum the carpets".

A vacuum is a volume of space that is substansively empty of matter, so that gaseous pressure is much less than standard atmospheric pressure. The root of the word vacuum is the Latin adjective vacuus which means "empty," but space can never be perfectly empty. A perfect vacuum, known as "free space", with a gaseous pressure of absolute zero is a philosophical concept with no physical reality, not least because quantum theory predicts that no volume of space is perfectly empty in this way.

They discuss ideal test results that would occur in a perfect vacuum, which they simply call "vacuum" in this context, and use the term partial vacuum to refer to the imperfect vacua realized in practice.

The quality of a vacuum is measured by how closely it approaches a perfect vacuum. The residual gas pressure is the primary indicator of quality, and it is most commonly measured in units of torr, even in metric contexts. Lower pressures indicate higher quality, although other variables must also be taken into account. Quantum mechanics sets limits on the best possible quality of vacuum. Outer space is a natural high quality vacuum, mostly of much higher quality than what can be created artificially with current technology. Low quality artificial vacuums have been used for suction for millenia.

Vacuum has been a common topic of philosophical debate since Ancient Greek times, but it was not studied empirically until the 17th century. Experimental techniques were developed following Evangelista Torricelli's theories of atmospheric pressure. Vacuum became a valuable industrial tool in the 20th century with the introduction of the light bulb and vacuum tube, and a wide array of vacuum technology has since become available. The recent development of human spaceflight has raised interest in the impact of vacuum on human health, and life forms in general.

Answer 7

The correct spelling of vacuum is V-A-C-U-U-M. In physics, vacuum is a space from which air or other gas has been exhausted to a very high degree.

Answer 8

1a space with nothing at all in it; completely empty space
2a) an enclosed space, as that inside a vacuum tube, out of which most of the air or gas has been taken, as by pumping b) the degree to which pressure has been brought below atmospheric pressure
3a space left empty by the removal or absence of something usually found in it; void: often used figuratively
>4short for VACUUM CLEANER
adj.
1of a vacuum
2used to make a vacuum
3having a vacuum; partially or completely exhausted of air or gas
4working by suction or the creation of a partial vacuum
vt., vi.
to clean with a vacuum cleaner In full vac$u[um-clean$

Answer 9

vacuum (n.) - [vaekjuëm] - 1. A space that is completely empty of all matter or gas; 2. A space in a container from which the air has been completely or partly removed; 3. A situation in which sb/ sth is no longer present and their/ its place has not yet been filled.

vacuum (v.) - to clean sth with a vacuum cleaner

Answer 10

A vacuum is a space which contains nothing.
