Density (Physics)

Summary: Take a look at Figure 5. Theatmospheric pressure at sea level is bigger than the atmospheric pressure high up a mountain. Gravitypulls the air particles towards Earth. Where the particles are closer,there are more collisions. The pressure is higher. Density is howclose the particles are in a substance. Gas has a higher density atsea level.
