To show Boyle’s Law, connect the calibrated syringe to the pressure gauge.
The entire class can view the corresponding pressure change as the volume of gas in the syringe is varied.
To show Absolute Zero, connect a metal sphere to the pressure gauge and immerse the sphere in water of different temperatures.
This is a good way to visualize the basic relationship between pressure, volume and temperature of gases.
Students can graph the results.
Read the pressure changes directly from the scale
