Abstract: | Summary Details of apparatus construction and refinements are presented for a micro capillary rise method of determining absolute values of surface tension. Experimental values of surface tension for benzene, n-pentadecane, and methyl laurate are recorded and compared with previous literature values. Parachors are determined. The method requires a minute amount of sample and is simple, quick, precise, and accurate. Published with the approval of the Director of Research, North Carolina Agricultural Experiment Station, as Paper No. 576 of the Journal Series. |
