Designed for Boyle’s Law demonstration in wide pressure ranges to a group of students, results
can be observed even from a distance.
The apparatus comprises a thick walled, wide-bore glass tube mounted vertically in front of a
scale graduated 0 to 65cm3, with closed end of the tube at the top and open bottom end
secured tightly on the thick-walled metal tube with O-ring to get leak proof joint.
Other end of metal tube connected to a cylindrical oil chamber filled with colored oil and
capable of withstanding high pressures.
Zero of the scale corresponds to the inside of the closed (top) end of the tube with the scale
reading directly indicating volume of air enclosed in the tube.
Oil chamber fitted with Bourdon gauge at the top, calibrated 0-3.4 × 105 Nm-2 and has a valve
on one side for connection to air compression pump.
