Boyle-Mariotte Law Experiment

The Boyle-Mariotte Apparatus consists of a closed plexiglass cylinder with a sliding piston that determines the enclosed volume, a scale for volume determination and a manometer for pressure determination. The piston is displaced by turning a threaded rod with crank. For safety reasons, the working cylinder is additionally surrounded by a protective cylinder made of acrylic glass. By means of a ventilation valve, pressure can be equalized with the ambient air in any piston position. Subsequent displacement of the piston generates overpressure or vacuum, depending on the initial situation.

Technical data:

Consists of acrylic tube graduated from 0 to 300cm mounted horizontally.

Inner diameter: 45 mm

Maximum pressure: 370 kPa

Objects of experiment:

+ Measuring the pressure p of the enclosed air at room temperature for different positions s of the piston.

+ Displaying the measured values for three different quantities of air in the form of a p-V diagram

+ Verifying Boyle’s Law.
