Surface tension of filmex in dynes/cm

WebOct 1, 1998 · Abstract and Figures. This paper is a review of work on thin fluid films where surface tension is a driving mechanism. Its aim is to highlight the substantial amount of … Websurface tension increases as the intermolecular attraction increases and the molecular size decreases. For most oils, σ ∼ 20 dynes/cm, while for water, σ ∼ 70 dynes/cm. The highest surface tensions are for liquid metals; for example, liquid mercury has σ ∼ 500 dynes/cm. The origins of interfacial tension are analogous.
