About This Product
Students note the starting temperature and pressure, heat the chamber gradually and record the pressure at several temperatures once the readings settle. Plotting pressure against absolute temperature gives a straight line, verifying Gay-Lussac’s law and linking it to the kinetic theory of gases. The chamber must not be overheated, and the apparatus is left to cool before it is put away.
Frequently Asked Questions
What does the Gay-Lussac’s Law Apparatus show?
