What is Understanding Pressure in Physics about?
Pressure is defined as force per unit area. In liquids, pressure increases with depth and density and acts equally in all directions. Atmospheric pressure decreases with increasing altitude, exerting greater pressure outside an empty container than inside, causing it to crush. A barometer measures atmospheric pressure using the height of a mercury column, with one atmosphere equaling 101,300 Pascals or 760 mmHg. A manometer compares fluid pressures to atmospheric pressure using U-tube columns of liquid.
