How Does Surface Tension Balance Small Objects on Water Surface?

[QUOTE="ergospherical, post: 6550212, member: 691758"] It's much more subtle than that! There are surface tension terms associated with interfaces of any phases, e.g. ##\gamma_{LS}## for liquid-solid, ##\gamma_{LV}## for liquid-vapour, etc., each defined as the derivative ##\dfrac{\partial E}{\partial A}## of free energy with respect to the area of that type of interface. Capillary action arises because systems can lower their energy by extending certain interfaces at the expense of other interfaces! [/QUOTE]
