Pressure is a fundamental concept in physics that refers to the force applied per unit area. It is a measure of how much force is being exerted on an object or substance over a given area. Pressure plays a crucial role in daily life and has diverse scientific applications.

In everyday situations, we encounter pressure in various forms. For instance, when we blow up a balloon, the air molecules inside exert a force on the walls of the balloon, creating internal pressure. This pressure is what keeps the balloon inflated. Similarly, when we step on the gas pedal of a car, the exerted force increases the pressure in the combustion chamber, leading to the controlled explosion that powers the vehicle.

In scientific disciplines, pressure is essential for understanding and studying various phenomena. It helps us explain how liquids flow through pipes, how gases behave under different conditions, and even how living organisms maintain blood circulation through blood vessels.

To summarize, pressure is a measure of force over a given area and is present in both everyday life and scientific applications.
