What is an example of atmospheric pressure?

An example of atmospheric pressure is the ability of ink to fill a pen.

Atmospheric pressure, which is the force exerted by the weight of air above a given point, plays a crucial role in many everyday phenomena. Let's explore further:

  • Ink in a Pen: When you use a fountain pen or a similar ink-filling device, the atmospheric pressure helps push the ink into the reservoir. A pressure difference is created when you draw ink out, and the higher atmospheric pressure outside the pen forces the ink to flow in to equalize the pressure.

  • Suction Cups: Similar to the lizard example, suction cups work because they create a partial vacuum between the cup and the surface. The atmospheric pressure then pushes the suction cup against the surface, providing the force that holds it in place.

  • Breathing: Our lungs expand and contract to create pressure differences. Atmospheric pressure helps air flow into our lungs when we inhale (creating lower pressure in the lungs) and out when we exhale (creating higher pressure in the lungs).

In summary, atmospheric pressure is a ubiquitous force that enables various natural and man-made processes.
