In this experiment, we modeled a microscopic system of gasses by using motorized squiggle balls to represent the molecules. By examining the forces exerted by systems of varying molecular number and area, we were able to find an equation of state for a macroscopic system in two dimensions. We observed systems composed of three, four, five, and six molecules in areas ranging from 15 to 55 cm in length. The found equation of state was then applied to a system of two “gasses” in a mechanical interaction. We observed systems of three vs. three, and four vs. two balls interacting through a moveable piston. Using the laws of multiplicity and probability, we were able to find an equation for the probability of the piston’s location in systems with varying molecular numbers. Although our results were comparable to the interactions that occur on the microscopic level, they are not completely accurate because temperature was not a parameter in our system.
