High pressure.The air simply follows the gradient and rushes in to fill the gap. 2. Weather and Wind
Fluids (gases and liquids) always flow from regions of high pressure to regions of low pressure . The greater the difference, the faster the flow. What Is Pressure Difference
The old adage "nature abhors a vacuum" is actually a layman's way of saying "nature seeks pressure equilibrium." High pressure
This principle applies to:
We often think of pressure as a static measurement—checking tire pressure or monitoring blood pressure—but in the physical world, pressure is rarely about the number itself. It is about the relationship between two numbers. It is the difference between high and low that creates motion, energy, and force. The greater the difference, the faster the flow
is defined as force per unit area: ( P = \fracFA ) (Pascals, Pa, or N/m²).
