An approximation to dis vacuum na area wey get gaseous pressure wey dey much less pass atmospheric pressure. Physicists dey often talk about ideal test results wey fit happen for perfect vacuum, wey dem sometimes just dey call "vacuum" or free space, and dem dey use di term partial vacuum to refer to an actual imperfect vacuum as one fit get for lab or for space. For engineering and applied physics on di other hand, vacuum dey refer to any space wey di pressure dey lower pass atmospheric pressure. Di Latin term in vacuo dey used to describe an object as e dey inside wetin suppose be vacuum.```
