<P> Surface tension is dependent on temperature . For that reason , when a value is given for the surface tension of an interface , temperature must be explicitly stated . The general trend is that surface tension decreases with the increase of temperature , reaching a value of 0 at the critical temperature . For further details see Eötvös rule . There are only empirical equations to relate surface tension and temperature : </P>
state the relationship between the surface tension and the temperature of water
decreases with the increase of temperature
