Which of the following statement is not true about amorphous solids? (a) On heating, they may become crystalline at certain temperature. (b) They may become crystalline on keeping for long time. (c) Amorphous solids can be moulded by heating. (d) They are anisotropic in nature.

Although amorphous solids do not posses the long range order of crystals, they do have ……… just as liquids do.

Why amorphous solids are called isotropic whereas crystalline solids are called anisotropic ?

The amorphous solid among the following is
