Homonym: vacuums (Empty)
A vacuum is a space that is completely empty of matter, including air. In scientific terms, it refers to a region where the pressure is significantly lower than atmospheric pressure. Vacuums are commonly created in laboratories and are essential for various experiments, such as those involving particle physics or vacuum packaging.
In everyday life, the term "vacuum" often refers to a vacuum cleaner, a device that uses suction to remove dirt and debris from floors and other surfaces. These machines work by creating a partial vacuum that draws in air and particles, making cleaning more efficient.
