Students may suggest placing an equal number of drops of each liquid on wax paper, overfilling a test tube, or comparing the number of drops that can be added to the top of a penny. However, surface tension is ~ 1/3 in alcohols compared to that of water because of their very week polar nature. water striders), usually denser than water, to float and slide on a water surface. Surface tension values of some common test liquids for surface energy analysis. Surface Tension [mN/m] State Reference; 293.15: 22.0000: Liquid: 4: 293.15: 22.2900: … Name: CAS Ref.-No. Surface tension values of common test liquids. Surface tension allows insects (e.g. Surface tension is caused by the inward attraction of molecules at a boundary. Surface tension measurements of aqueous 1-alkyle-3-methylimidazolume tetrafluoroborate {[Cnmim][BF4] (n = 2, 4, 6)} solutions and modeling surface tension of ionic liquid binary mixtures using six various models. This is a table of surface tension values for some interfaces at the indicated temperatures. … Surface Tension (γ) of Ethanol (11%) at 25°C is 46.03 dyne/cm Convert 46.03 dyne/cm to different units Ask students: How could we compare the surface tension of water and alcohol? Have students compare the surface tension of water and alcohol. Surface … Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible.
