About This Product
Raising or lowering the reservoir changes the pressure on a trapped column of air, and students read its length on the scale at each setting. Plotting pressure against volume, or against the reciprocal of volume, shows the inverse relationship described by Boyle’s law. Laboratories and colleges in Guinea-Bissau, Barbados, Albania, Peru, Luxembourg and Madagascar can buy the Boyle’s Law Apparatus through an export order.
Frequently Asked Questions
How is the pressure changed on the Boyle’s Law Apparatus?
By moving the mercury reservoir clamp up or down its metal rod. The scale reads in mm in both directions.
