Atmospheric Pressure
  • Atmospheric pressure at sea level is about 14.7 pounds per square inch. This pressure is the equivalent of the weight of two large elephants pushing on every of surface.

Slide 17 - Tekstslide

Effects of atmospheric pressure
  • The effect of atmospheric pressure can be shown by pumping the air out of a metal container.
