Description

Apparatus for the
recording of pressure
versus volumes and for
investigating Boyle’s
Law. The vertical tube
is part-filled with the
coloured liquid and
sealed. The trapped
air is then compressed
progressively, with
pressure (p) and volume (v) readings taken at
each stage. Before each pair of readings is taken,
the liquid should be allowed to settle so that the
heat caused by the compression is dissipated.
Pump and oil included.
