Abstract

This article details the construction of a three-story tall water barometer and outlines several important chemical principles that can be explored with such a device. Not only can students develop an intuitive understanding of pressure and how a barometer works, the experiment can be extended to explore vapor pressure, phase changes, equilibrium, and gas solubility. This experiment is inexpensive to set up and can be easily completed in less than an hour.
