EFFECT OF PRESSURE ON STYROFOAM CUP
120lb psi is exerted on a styrofoam cup
Two styrofoam cups are compared before and after being exposed to 120 lbs of pressure per square inch, equivalent to eight atmospheres. The outside pressure forces air molecules to be released, causing the syrofoam to increase density and shrink in size.
