When the stored energy increases, so does the length of the molecular bonds. As a result, solids typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed by its coefficient of thermal expansion. Different coefficients of thermal expansion can be defined for a substance depending on whether the expansion is measured by: * linear thermal expansion * area thermal expansion * volumetric thermal expansion These characteristics are closely related. The volumetric thermal expansion coefficient can be defined for both liquids and solids. The linear thermal expansion can only be defined for solids, and is common in engineering applications. Some substances expand when cooled, such as freezing water, so they have negative thermal expansion coefficients. For exactly isotropic materials, the area thermal expansion coefficient is very closely approximated as twice the linear coefficient."""^^rdf:HTML ; rdfs:isDefinedBy ; rdfs:isDefinedBy qudt:science ; rdfs:label "Area Thermal Expansion Unit" ; rdfs:subClassOf qudt:ThermalExpansionUnit ; rdfs:subClassOf [ rdf:type owl:Restriction ; owl:hasValue quantitykind:AreaThermalExpansion ; owl:onProperty qudt:hasQuantityKind ; ] ; . qudt:AreaTimeTemperatureUnit rdf:type owl:Class ; dct:description "A sub-type of 'Thermodynamics Unit'.

The canonical example of extrinsic curvature is that of a circle, which has curvature equal to the inverse of its radius everywhere. Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point.

The osculating circle of a sufficiently smooth plane curve at a given point on the curve is the circle whose center lies on the inner normal line and whose curvature is the same as that of the given curve at that point. This circle is tangent to the curve at the given point. That is, given a point P on a smooth curve C, the curvature of C at P is defined to be \\(1/R\\) where \\(R\\) is the radius of the osculating circle of \\(C\\) at \\(P\\). The magnitude of curvature at points on physical curves can be measured in diopters (also spelled \"dioptre\"), a convention in optics.

Electric Current Density is a measure of the density of flow of a conserved charge. Usually the charge is the electric charge, in which case the associated current density is the electric current per unit area of cross section, but the term current density can also be applied to other conserved quantities.

Fluid dynamics offers a systematic structure that underlies these practical disciplines and that embraces empirical and semi-empirical laws, derived from flow measurement, used to solve practical problems.

The chief characteristic of hypersonic aerodynamics is that the temperature of the flow around the aircraft is so great that the chemistry of the gas must be considered. At low hypersonic speeds, the molecular bonds vibrate, which changes the magnitude of the forces generated by the air on the aircraft. At higher hypersonic speeds, the molecules break apart producing an electrically charged plasma around the aircraft. Large variations in air density and pressure occur because of shock waves, and expansions. Hypersonic aircraft typically have very thick boundary layers along the surface and high heat transfer to the surface.

Orbital mechanics focuses on spacecraft trajectories, including orbital maneuvers, orbit plane changes, and interplanetary transfers, and is used by mission planners to predict the results of propulsive maneuvers.

Ionization can be induced by other means, such as strong electromagnetic field applied with a laser or microwave generator, and is accompanied by the dissociation of molecular bonds, if present. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic fields. Plasma, therefore, has properties quite unlike those of solids, liquids, or gases and is considered a distinct state of matter. Like gas, plasma does not have a definite shape or a definite volume unless enclosed in a container; unlike gas, under the influence of a magnetic field, it may form structures such as filaments, beams and double layers. Some common plasmas are found in stars and neon signs. In the universe, plasma is the most common state of matter for ordinary matter, most of which is in the rarefied intergalactic plasma (particularly intracluster medium) and in stars.

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (and for fluids only), viscosity is \"thickness\" or \"internal friction\". Thus, water is \"thin\", having a lower viscosity, while honey is \"thick\", having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity). Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them.

Formally, viscosity (represented by the symbol \\(\\eta\\) (\"eta\") is the ratio of the shearing stress (\\(f/A\\)) to the velocity gradient (\\(\\Delta v_x / \\Delta z\\) or \\(dv_x / dz\\)) in a fluid.

The SI quantity quantity for viscosity is sometimes called dynamic viscosity, absolute viscosity, or simple viscosity, but is usually just called viscosity.
