The tensions were measured using a Du Nouy Ring Tensiometer and an EZ Tensiometer Model 101. The Du Nouy Tensiometer is a method that uses a platinum ring that was pulled through a liquid’s surface. To calibrate the tensiometer five strips of paper were used cumulating weight. The surface tension is the maximum force needed to detach the ring from the liquid surface. The force was measured using tap water, kerosene, and interfacial tension was measured using the platinum ring on the interface of the two fluids. The other instrument that was used to calculate surface tension was the EZ tensiometer. A sample of kerosene and tap water were each placed into a beaker and onto an electronic scale. A draft shield was placed around the beaker and the tensiometer was placed into the fluid. The dial was turned at the top, which raised the tip, and the tensiometer was placed into the fluid....
