Pressure vs. Volume and Boyle’s Law SCIENTIFIC

Use the kinetic theory to explain the results of Boyle’s experiment. 4. The pressure scale on a tire gauge is marked in units of pounds per square inch (psi). The scale starts at zero when the gauge is exposed to the surrounding air. This means that the total pressure is equal to the gauge pressure plus the pressure of the surrounding air.
