NEGATIVE PRESSURE Meaning and
Definition
-
Negative pressure refers to a condition in which pressure within a given area or system is lower than the atmospheric pressure or the surrounding environment. It occurs when the force exerted on a surface or object is less than the usual amount of force experienced under normal conditions.
In the context of fluids or gases, negative pressure can be created by removing air, thereby leading to a partial vacuum or a state of reduced pressure compared to the surroundings. This state allows for the movement of fluids or gases from an area of higher pressure to an area of lower pressure. This concept plays a significant role in various scientific fields, such as engineering, physics, and medicine. For instance, in medical settings, negative pressure rooms are designed to control the spread of airborne infections by maintaining lower pressure inside while ensuring contaminated air does not escape.
Negative pressure is also encountered in mechanical systems, such as pumps or suction devices, where it is employed to create a pressure difference to draw materials or substances towards a lower pressure region. By harnessing negative pressure, substances can be effectively moved or extracted.
Overall, negative pressure refers to a state in which pressure is below atmospheric levels, allowing for the movement or extraction of substances, controlling environments, or facilitating various processes in scientific, engineering, and medical applications.

Etymology of NEGATIVE PRESSURE
The word "negative pressure" is composed of two parts: "negative" and "pressure".
1. "Negative": The word "negative" originates from the Latin word "negativus", which is derived from the verb "negare", meaning "to deny" or "to refuse". It entered the English language in the late 14th century and initially referred to the contradictory or opposite sense of something. Over time, "negative" expanded to convey meanings like "lacking" or "absence of".
2. "Pressure": The term "pressure" has its roots in the Latin word "pressura", which stems from the verb "pressus", meaning "to press" or "to squeeze". The word entered English usage in the 14th century and refers to the physical force per unit area exerted on an object or substance.
