Demonstration
Finding the density of air. Using a crop sprayer, pump it up to increase the pressure; use a balance to find the mass of the crop sprayer. Release the compressed air in the crop spryer through a beehive into a water filled measuring cylinder. Measure the new mass of the crop sprayer.
Resources
Analysis
Use p=m/V to find the density.
Equipment
1x crop sprayer, 1x beehive, 1x pipes, 1x large measuring cylinder, 1x large water basin & scales
Safety
pressurised container, do not over pressurise.
