Question

Steno's law in solid states is abt

Answer 1

Steno’s law, statement that the angles between two corresponding faces on the crystals of any solid chemical or mineral species are constant and are characteristic of the species; this angle is measured between lines drawn perpendicular to each face. The law, also called the law of constancy of interfacial angles, holds for any two crystals, regardless of size, locality of occurrence, or whether they are natural or man-made.
