JCE Classroom Activity
JCE Classroom Activity: Out of "Thin Air": Exploring Phase Changes
John J. Vollmer
Department of Chemistry, Mills College, Oakland, CA 94613
Cover
April 2000
Vol. 77 No. 4
p. 488A
Abstract
Most students easily understand melting, vaporization, boiling, condensation, and freezing based on their daily experiences with water. The conversion of a solid directly to a gas, sublimation, and the conversion of gas to solid, deposition, may be more difficult to grasp because they are unfamiliar. Seeing these phase changes alongside evaporation and condensation may help students to better understand these processes. This Activity illustrates sublimation/deposition with para-dichlorobenzene (mothballs) and evaporation/condensation with water.
