DROPS ERNESTO CANOSSA PHOTOGRAPHY
Why are drops spherical: Surface tension its the property of liquids by which surface molecules of a liquid try to hold the liquid together by acquiring minimum surface area and acting like a stretched membrane inside a drop, each molecule is pulled with a force by its neighboring molecules as this forces are equal and opposite, they get neutralized however, the molecule present at the surface it’s not attracted outwards it is attracted only inwards and sideways, sideways forces get neutralized but because the inward force each surface molecule contracts to form a shape that has a minimum surface area which is a sphere
