Why "A falling drop of liqiud is sherical"?

Question

Related to chemistry.

Answer 1

The cohesive force called the surface tension will bring the molecules close and close together

WHen a drop of liquid is suspended in air the continuous action of the Surface tension will try to bring down the surface as low as possible to have minimum force tending to be stable.

Given a volume the least surface area that can contain this volume is a sperical shape and not any other shape. So the surface tension will ultimately make the liquid attain a shperical shape to have the least surface area.

Answer 2

The sphere is the most economical and perfect form in nature.

When you have a liquid of any type, it will always take the shape of a sphere, even on a table, it wants to become on, as you see a round dome on the water drop on a waxed table.

As the dome shifts and evaporated it condenses upon itself and closes in on the bottom. But, because of gravity on the water drop, pushing it against the table it cant form a sphere, so it forms the next best thing, a half bubble.

Ok, enough babbling for me today...

I wish you well..

Answer 3

cohesion and surface tension...of the liquid due the chemical bonding between them...

if it's water then it's hydrogen bonding and van derwaals
the one that really play an important role is hydrogen bonding.

Answer 4

It's because water is cohesive; it sticks to itself. As it pulls in as closely to itself as it can, it becomes a sphere to minimize surface area.

Answer 5

because thats the fastest route to the ground the most aerodynamic.

Answer 6

it is as a result of its own liquid Potential Energy

Answer 7

surface tension and gravity
