Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other. But their properties are, of course, enormously different. While a solid …
WebMar 20, 2024 · Crystal Meth. Powdered meth can be converted into crystal meth, a more potent form of the drug that resembles shiny fragments of glass, quartz or rock salt. Crystal meth is made by dissolving meth powder in a solvent, such as acetone or denatured alcohol. As the mixture evaporates, crystals form around the edge of the mixing container. WebA crystalline substance is a solid material in which the atoms, molecules, or ions are arranged in an orderly, repeating pattern extending in all three spatial dimensions. Crystalline substances are characterized by their high degree of symmetry and regularity, which results in distinctive physical and chemical properties.
