In this work, the surface tension of fatty acids (FA) is correlated to Martin&#8217;s rule of free energy additivity for estimating surface tension. The proposed equations for estimating the surface tension of FAs are correlated to the number of carbon atoms (z), the number of double bond (s) (nd) and temperature (T) to \u03b3 = 69.065\u22121.3614z\u22120.13895T+0.005209zT+6.24n<sub>d<\/sub>\u22120.01612n<sub>d<\/sub>T. The proposed equations are easy to use and the estimated values of surface tension of FA at different temperatures agree well with the literature values.<\/p>\n<hr \/>\n<h2 class=\"section-title u-h3 u-margin-l-top u-margin-xs-bottom\"><span style=\"font-size: 20px;\">Keywords<\/span><\/h2>\n<div id=\"kw0005\" class=\"keyword\">\n<div id=\"kw0005\" class=\"keyword\">\n<div id=\"kw0005\" class=\"keyword\">\u00a0<\/div>\n\u00a0<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p> [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[12],"tags":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/posts\/1617"}],"collection":[{"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/comments?post=1617"}],"version-history":[{"count":1,"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/posts\/1617\/revisions"}],"predecessor-version":[{"id":1619,"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/posts\/1617\/revisions\/1619"}],"wp:attachment":[{"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/media?parent=1617"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/categories?post=1617"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/force.kmutt.ac.th\/wp-json\/wp\/v2\/tags?post=1617"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
