Crystalline solids can be ionic, molecular, covalent network, or metallic.
10.5: Solids Solids can be divided into amorphous solids and crystalline solids.All liquids experience capillary action, demonstrating either capillary rise or capillary depression in the presence of other substances. All liquids experience surface tension, an imbalance of forces at the surface of the liquid. If volume is limited, evaporation eventually reaches a dynamic equilibrium, and a constant vapor pressure is maintained. 10.4: Properties of Liquids All liquids evaporate.All phase changes occur with a simultaneous change in energy. Video Transcript Solids, liquids and gases. 10.3: Phase Transitions - Melting, Boiling, and Subliming Phase changes can occur between any two phases of matter. particles are arranged in solids, liquids and gases.The preferred phase of a substance depends on the strength of the intermolecular force and the energy of the particles. Substances with covalent bonds between an H atom and N, O, or F atoms experience hydrogen bonding. For any pure substance, the temperature at which melting occurs known as the melting point is a characteristic of that substance. The opposite process, a liquid becoming a solid, is called solidification. Substances that are polar experience dipole-dipole interactions. The process of a solid becoming a liquid is called melting (an older term that you may see sometimes is fusion ). 10.2: Intermolecular Forces All substances experience dispersion forces between their particles.Observers also point out that telescopes with glass lenses to focus light still do so even decades after manufacture-a circumstance that would not be so if the lens were liquid and flowed. This is how glass behaves: it goes back to its original shape (unless it breaks under the applied force). Solids may deform under a small force, but they return to their original shape when the force is relaxed. 10.1: Prelude to Solids and Liquids Liquids flow when a small force is placed on them, even if only very slowly.
