Taking units of joules per square meter, it results from discontinuity: while most molecules in a liquid are entirely surrounded by others, at interfaces they aren't, resulting in energy imbalances.
Taking units of joules per square meter, it results from discontinuity: while most molecules in a liquid are entirely surrounded by others, at interfaces they aren't, resulting in energy imbalances. It can be directly measured with a capillary tube, and explains why bubbles take spherical shapes: minimizing area minimizes energy. For 10 points—identify this property of fluids, because of which certain insects can "walk" on water.
