Which of the following is not a characteristic of a crystalline solid ?

(a) Definite and characteristic heat of fusion

(b) lsotropic nature

(c) A regular periodically repeated pattern of arrangement of constituent particles in the entine crystal

(d) A true solid

Solution

Answer: (b) lsotropic nature. Because the Crystalline solid is anisotropic in nature as this solid shows different physical properties such as electrical resistance, a refractive index in different directions.

Note Isotropic and anisotropic properties are related to amorphous solid and crystalline solid which can be clearly understooa as

$\begin{matrix} P r o p e r t y & T y p e s o f s o l i d & P h y s i c a l p r o p e r t i e s I s o t r o p y & A m o r p h o u s s o l i d & S a m e v a l u e A n i s o t r o p y & C r y s t a l l i n e s o l i d & D i f f e r e n t v a l u e s \end{matrix}$
