So, after visualizing the air particles in our syringe systems, we are ready to revise our patterns:
“When a syringe system is at rest (no one is pulling up or pushing down on a plunger), then the syringe system will always return to the standard air particle density.”
“The further a syringe system is from the standard air particle density, the harder it is to continue pulling up or pushing down on the syringe.”
The nice thing about these revised patterns is that they apply just as well to open systems as to closed systems. Being able to visualize the air particles in the syringe will be critical as we work to develop a theory to explain these patterns later in the unit, so continue exploring the single syringe simulator and the syringe pair simulator until you can accurately visualize the air particles in the syringe(s) on your own.
