Describe an experiment to verify Boyles’ law

• air in the closed limb of a U-tube barometer as shown above
• mercury is poured to a height, h, and the length of the air column, L is noted.
• the length h is varied to obtain different sets of values of h and L
• Pressure of the gas is calculated from P = (H + h)ρg where H= height of barometer corresponding to atmospheric pressure, ρ = density of mercury, g = acceleration due to gravity. Note that h can be positive or negative.
• If A is the cross section area, V =AL
• Values of h, L, P, V and 1/V are tabulated
• A plot of P against 1/V gives a straight line through the origin which verifies Boyle’s law.
