partial vacuum
Incomplete air removal
A partial vacuum is a space where air pressure is lower than the surrounding atmosphere but not completely absent.
Unlike a total vacuum, some gas molecules remain.
Partial vacuums power everyday devices—when you suck through a straw, you create one, and the higher pressure outside pushes liquid up.
The pump creates a partial vacuum to draw water from the well.
