Answer:

Vacuum is space devoid of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. ... For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%.
