Answer 2

Answer:

Glass is a substance which on cutting will give irregular cleavage.

Explanation:

Glass is an amorphous solid.  It does not form a crystalline solid structure as particles in solids do not move but here in amorphous solid it moves.  Hence it is called a supercooled liquid.

Amorphous solids do not have crystals but the particles have the tendency to flow like liquid, though it is a very slow process. These solids does not have a long-range order of arrangement of their constituent particles
