About This Item

Description

A volatile liquid is placed in a test tube and the tube is closed with a stopper with a hole in it. The test tube is placed in a hot water bath. The liquid vaporizes and excess vapors escape through the hole. The tube is then placed in an ice bath to quickly cool the vapor and cause it to condense. The mass of the tube is determined.
