In a solid, constituent particles (ions, atoms, or molecules) are closely packed together. The forces between particles are so strong that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a definite volume. Solids can only change their shape by an outside force, as when broken or cut.
Chain-melted state: Metals, such as potassium, at high temperature and pressure, present properties of both a solid and liquid. Wigner crystal: a crystalline phase of low-density electrons. Hexatic state, a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles. Ferroics
Definitions of solid vary as well, and depending on field, some substances can have both fluid and solid properties. [2] Non-Newtonian fluids like Silly Putty appear to behave similar to a solid when a sudden force is applied. [3] Substances with a very high viscosity such as pitch appear to behave like a solid (see pitch drop experiment) as well
An electrolyte is a substance that conducts electricity through the movement of ions, but not through the movement of electrons. [1] [2] [3] This includes most soluble salts, acids, and bases, dissolved in a polar solvent like water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the ...
The sudden application of force—by stabbing the surface with a finger, for example, or rapidly inverting the container holding it—causes the fluid to behave like a solid rather than a liquid. This is the " shear thickening " property of this non-Newtonian fluid.
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice. It is used mainly as a nutritional supplement and in organic chemistry.
Protic ionic liquids are formed via a proton transfer from an acid to a base. [26] In contrast to other ionic liquids, which generally are formed through a sequence of synthesis steps, [2] protic ionic liquids can be created more easily by simply mixing the acid and base. [26] Phosphonium cations (R 4 P +) are less common but offer some ...
This reaction occurs when two aqueous strong electrolyte solutions mix and produce an insoluble solid, also known as a precipitate. The ability of a substance to dissolve in water is determined by whether the substance can match or exceed the strong attractive forces that water molecules generate between themselves.
