WebDec 11, 2024 · Tar, glass, plastic, rubber, butter etc. are classified as amorphous solids. Amorphous solids do not have an ordered internal structure and do not melt at a definite, sharp melting point. With an increase in temperature, it gradually softens, becomes less viscous and melts over a range of temperatures.
WebCrystalline vs. Amorphous Ice These terms refer to the geometric arrangement of the molecules in the solid state form of water (ice).
