The relative viscosity of 2,2,4-trimethylpentane can be measured using a stopwatch, and compared to other liquids.
The relative viscosity of 1-pentanol can be measured using a stopwatch, and compared to other liquids.
Four funnels are connected to differing lengths of capillary tubing. The greater the length of the capillary tube, the longer it takes for the water to flow through the apparatus.
Carbon tetrachloride, water and hexane are used to show how polarity and density affect the interactions between substances.
