Is surface tension conservative?

    Hello, everybody. Is surface tension a conservative force? I think so, because it is related to surface energy. But I am not 100% sure. Thanks a lot.

    Interesting question.

    I think 'no', because the contact angle can assume a range of values (hysteresis, canthotaxis) and the surface will still be considered in thermodynamic equilibrium. On the other hand, the existence of capillary waves would seem to imply the converse.
