Types of Solids: Different types, Crystalline & Amorphous Solids

WebCrystalline solids have sharp melting points, that is, they change into liquids at definite temperatures. Amorphous solids, on the other hand, are thought to be liquids at all temperatures. This is because, on being heated, they do not abruptly change into liquids, but instead soften and start flowing in a semisolid form. WebAmorphous Solids. Amorphous solids are rigid structures but they lack a well-defined shape. They do not have a geometric shape. So they are non-crystalline. This is why they do not have edges like crystals do.
