*Calculate the pressure using the formula P = 1.03 + Mass on Syringe Area of Top of Syringe. This
formula adds the pressure from the
weight to the atmospheric pressure, 1.03 kg/cm2.
Graph: Enter all six (P, V) pairs into a regression calculator so that you can compute the power
regression equation VaPn
. (The x-variable is pressure, P, and the y-variable is volume, V.) How close
is the power, n, to the value -1, predicted
by Boyle's law?
