Question

if salt and sugar do not appear to have fixed shaped then why do we call solid?

Answer 1

Substances like salt and sugar do not have a definite shape when stored in a container because of their crystalline form.These substances usually have very tiny crystals which have a rigid structure and fix packed particles. Thus, the crystals are actually solids and thus the salt and sugar as a whole of a number of such crystals are referred to as solids. Hope this helps !!

Answer 2

but they have fixed composition with a shape which doesn't change itself until unless external factors are not applied.........
