Assume two solutions will be prepared at the same % weight/volume (w/v) concentration, using a monomer (D-(+)-glucose, also known as dextrose) and a polymer (2-hydroxyethyl cellulose). The polymer molecular weight is related to the degree of polymerization, where the degree of polymerization is the number of units that are covalently linked together to form the polymer. Glucose is a simple sugar that can be assembled in repeating units in beta-(1-4) linkages to form cellulose. Cellulose is an insoluble polymer found in plants. Chemical modification of cellulose by the addition of hydroxylated ethyl side-chains creates 2-hydroxyethyl cellulose, a more hydrophilic polymer that can be dissolved in water-based solutions.

- Would you expect the time in a time trial to be different for a particle falling through distilled water vs 5% glucose solution? Assume same amount of liquid and conditions (temp, etc.) for both trials. - Would you expect the time in a time trial to be different for a particle falling through 5% glucose vs 5% HEC90 solution?
