Y12 Viscosity Experiment

July 12, 2019

Year 12 students at Assumption College English Program study the viscosity of various liquids. A small sample of each liquid was put in a test tube and the time taken for a small bubble of air to rise through the liquid was recorded.

The viscosity of a liquid is a measure of its resistance to deformation. For liquids, it corresponds to the concept of “thickness”; for example, honey has a higher viscosity than water. The viscosity of seven common household liquids was measured with this technique and the values arranged in ascending order.
