2007 IMPACT OF TEMPERATURE ON VISCOSITY "Viscosity is the virtue by which a fluid offers resistance to the motion of a solid through it." This document reports on an experiment that examined the relationship between temperature and viscosity. The terminal velocity and up-thrust experienced by a sphere of fixed weight and radius was calculated by dropping it into a measuring cylinder filled with glycerol heated to different temperatures. Using Stokes Law viscosity corresponding to each temperature level was worked out. This generated a range of data points with viscosity corresponding to each temperature level. These data points were statistically analysed. The results corresponded to those indicated by theory i.e. temperature and viscosity are inversely related; as temperature increased viscosity decreased. This report is in five sections. The first details the plan and the science on which the experiment is based. The second describes implementation while the third analyses the results. The...
