Air Pressure and Boiling Point at Various Altitudes, Schemes and Mind Maps of Earth, Atmospheric, and Planetary Sciences

A table indicating air pressure at different elevations above and below sea level, as well as the corresponding boiling points of water. The data can be used for various scientific and engineering applications.

What you will learn

  • What is the boiling point of water at an altitude of 5,000 feet?
  • What is the air pressure at an altitude of 2,000 feet?
  • How does air pressure change as altitude increases?
