... in keeping the temperature constant, and in accurately marking the liquid level with a pen. Nevertheless, the capillary rise method proved to be comparatively reliable, provided that proper technique is observed. Results of the capillary rise experiment for the effect of acetic acid somehow agreed with results from previous studies. INTRODUCTION Surface tension occurs due to cohesive forces (attractive forces acting between like molecules) pulling the surface molecules toward the body of the liquid. Furthermore, these surface molecules exhibit stronger cohesive forces upon neighboring molecules compared to the rest of the liquid. Thus, a droplet of water on a table will assume a roughly spherical or globular shape. From experience we also observe that it is more difficult to move an object through the surface of a liquid than to move it when it is completely submersed. In this study, the surface tension of dilute aqueous solutions will be measured. ...
