The preparation of diamonds in industrially, carbon changes its state from _ (crystalline/amorphous) to _ (crystalline/amorphous) form.

Solution

In the industrial preparation of diamond, high pressure is applied to graphite to prepare diamond.
Since graphite is amorphous state and diamond is in the crystalline state, so carbon changes its state from amorphous to crystalline.

Therefore, the correct answer is amorphous.
