Abstract
A simple experiment for demonstration of phase diagram of carbon dioxide has been developed. The experiment involves the compression of small pieces of dry ice and carbon dioxide gas mixture in a 1-mL tuberculin syringe with the needle end of the syringe sealed. During the course of the experiment, equilibrium exists from between solid and gas, to solid, liquid and gas, and finally to liquid and gas phases of carbon dioxide. The experiment is simple and easy to perform and can be completed in minutes.

Maria Oliver-Hoyo and William L. Switzer III, Robert EiermanJournal of Chemical Education2005 82 (2), 251This demonstration builds upon the commonly performed liquefaction of air not only to show the presence of nitrogen and oxygen, but also the presence of two other components, carbon dioxide and water. Several extensions are suggested: one to show boiling ...
Use of a Tea Infuser To Submerge Low-Density Dry Ice
Carl P. Fictorie , Ed VitzJournal of Chemical Education2004 81 (10), 1473Use of a Tea Infuser To Submerge Low-Density Dry Ice
Carl P. Fictorie , Ed VitzJournal of Chemical Education2004 81 (10), 1473A tea infuser is used as a container to hold low-density dry ice. When used with the classic demonstration where dry ice is used to acidify a solution in a graduated cylinder, the dry ice is suspended in the middle of the cylinder, allowing the solution ...
Equations of State and Phase Diagrams
L. GlasserJournal of Chemical Education2002 79 (7), 874Equations of State and Phase Diagrams
L. GlasserJournal of Chemical Education2002 79 (7), 874Equations of state (for example, the ideal gas equation) contain three (or more) variables and should therefore be graphically represented by three (or more!)-dimensional diagrams. Three-dimensional diagrams and models are quite common for single-phase ...

Pamela Mills , William V. Sweeney and Waldemar CieniewiczJournal of Chemical Education2001 78 (10), 1360We have a designed a workshop that uses a handmade device to illuminate the concepts of heat, work, energy transfer, and thermodynamic path. The workshop, appropriate for general chemistry students, is done in two parts. In the first, students focus on ...

Stephen A. GramschJournal of Chemical Education2000 77 (6), 718Recent research in the area of high-pressure geophysics has led to the discovery of extremely rich phase behavior in many important chemical systems at elevated pressures and temperatures and has yielded new insights into the electronic factors that ...
