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.
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.
