True or false
1. It is more common for a solid to have a higher density than a liquid.
2. The dispersion forces decreases with increasing atomic size.
3. Lower molecular forces allows freer movement.
Using your polymeric materials data collection and sorting table you or your class/team produced, please answer the following questions on a separate sheet of paper.
