| Abstract: | The traditional measuring method on the liquid volumetric expansion coefficient in laborato- ry is tedious, labor intensive, costly, and a waste of time. Due to these disadvantages, we design the measuring instrument by using optical lever system. The temperature of the liquid in the test tube changes slowly. By observing the change in liquid height using the optical lever system,we can get the liquid volumetric expansion coefficient precisely. |
