Why Are Small Drops Of Liquid And Bubbles Spherical?

1.	Why Are Small Drops Of Liquid And Bubbles Spherical?
Answer» We know that a liquid air interface costs energy, so that for a GIVEN VOLUME, the most stable surface is one which has the least surface area, which is a SPHERE. Thus, if gravity and other forces (like air RESISTANCE) are neglected, liquids drops and bubbles would be spherical. We know that a liquid air interface costs energy, so that for a given volume, the most stable surface is one which has the least surface area, which is a sphere. Thus, if gravity and other forces (like air resistance) are neglected, liquids drops and bubbles would be spherical.
