Question

Removing more air from a space than is brought into that space is an example of

a) ventilation
b) positive air pressure
c) negative air pressure
d) make up air

Answer 1

Negative air pressure is pressure lower than the atmospheric pressure. This can occur when more air is removed from a space than is brought into it.

Step-by-step explanation:

Negative air pressure is pressure lower than the atmospheric pressure. This can occur when more air is removed from a space than is brought into it. For example, when you open a vacuum-sealed jar, the pressure inside the jar decreases, creating a negative pressure. This can also happen in a building when outdoor air is removed faster than it enters, creating a negative air pressure inside.
