Question

liquid drop assume pherical shape. why?​

Answer 1

Answer:

The free surface of a liquid drop tries to acquire a spherical shape because a drop always tends to acquire minimum surface area for least surface tension. The liquid drop tries to pull in all the liquid on the surface inside, towards its center. Note that for given volume, the surface area of the sphere is minimum.

Answer 2

Explanation:

The basic chemical structure is that of ammonia (NH3) with the key atom being the central nitrogen atom. Try to remember that an amine is just like ammonia because ammonia is a simple molecule to recall. ... Primary amines are called things like methylamine (CH3-NH2) and ethylamine (CH3-CH2-NH2).
