Chemistry Everyday for Everyone
The Egg in the Bottle Revisited: Air Pressure and Amontons' Law (Charles' Law)
Louis H. Adcock
University of North Carolina at Wilmington, Department of Chemistry, Wilmington, NC 28403-3297
Cover
December 1998
Vol. 75 No. 12
p. 1567
Abstract
The "egg in the bottle" is a classic demonstration of Charles' law (P, T) found in many books of chemical demonstrations aimed primarily at elementary and high school students. Unfortunately, most of the explanations of the experiment are misleading and incorrect, many involving a shrinkage of the gas volume in a closed container. The correct interpretation of Charles' law is given along with some additional variations of the experiment.
