The experimental results confirmed that pressure and volume are inversely related, reaffirming Boyle's Law (pressure and volume are inversely proportional). The power regression confirmed this. +} + +\justification{ + As partially explored in the claim, increased pressure pushes gas molecules together---decreasing volume. This experiment measures those two features well because the book and extra weights placed on top of the syringe's plunger confer an equally distributed force to the part of the plunger inside the syringe, forcing the air to "push back" harder than if there were no weight at all in order to maintain equilibrium. The only other property of the air in the syringe which can change is volume (which is unconstrained by any other variable than pressure), so equilibrium is always maintained by the volume changing in proportion with Boyle's Law. +} + +\makedoc +\bye -- cgit
