Polystyrene and Styrofoam
1. The problem statement, all variables and given/known data
Devise and preform an experiment to determine what fraction of the volume of a sample of Styrofoam is air. We know that Styrofoam is made of Polystyrene with air bubbles. The mass is the same, the volume is different.
2. Relevant equations
3. The attempt at a solution
Well I thought that If I find the density of both the samples (Polystyrene and the Styrofoam) and find the difference and divide it by the density of the Polystyrene I could find the fraction of air, but I'm not very sure.
