Answer to Question 1

In the polymer structure of polystyrene there is a pendent chlorine atom. This not only prevents the polymer from close packing but also makes it solvent sensitive. The samples would swell with the elevated temperature or water and the polarity of acetone. The free chlorine bonds to the polar water or acetone. The cooking oil wouldn't have this effect as it isn't a polar substance.

Answer to Question 2

This aspect can greatly increase profits as it is viewed as a basis for customer satisfaction, not only with the product itself, but with the service from the company.
