With the increasing of temperature, intermolecular distance rises so that the inte-
raction force decreases. So, the viscosity coefficient will decrease when the tempera-
ture increases. From the fig.4, we can know that temperature dependence of the vis-
cosity is exponential, which is consistent to the theory.

Summary
The software—Flash provides an alternative approach in the time and distance mea-
surement, while Web camera is not only used to capture interesting physical pheno-
mena but also used for data acquisitions in many cases. The utilization of a web
camera connected to PC allows us to record the motion of the objects which is very
helpful to solve many kinematics problems.
