When latent heat is added, no temperature change occurs. This energy breaks down the intermolecular attractive forces, and also must provide the energy necessary to expand the gas (the pΔV work). Latent heat is the amount of heat added to or removed from a substance to produce a change in phase. Latent Heat of Vaporization of Fluorine is 3.2698 kJ/mol. Latent Heat of Fusion of Fluorine is 0.2552 kJ/mol. When expressing the same phenomenon as an intensive property, the heat capacity is divided by the amount of substance, mass, or volume, thus the quantity is independent of the size or extent of the sample. Heat capacity C has the unit of energy per degree or energy per kelvin. Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system. Fluorine – Specific Heat, Latent Heat of Fusion, Latent Heat of Vaporization It is usually expressed as a fractional change in length or volume per unit temperature change. Thermal expansion is generally the tendency of matter to change its dimensions in response to a change in temperature. Linear thermal expansion coefficient of Fluorine is - µm/(m Coefficient of Thermal Expansion of Fluorine Note that Fourier’s law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and gases. It is a measure of a substance’s ability to transfer heat through a material by conduction. The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. Thermal conductivity of Fluorine is 0.0279 W/(m Note that, these points are associated with the standard atmospheric pressure. There are 14 general types of such patterns known as Bravais lattices.įluorine – Melting Point and Boiling Point It is this repeated pattern which control properties like strength, ductility, density, conductivity (property of conducting or transmitting heat, electricity, etc.), and shape. The forces of chemical bonding causes this repetition. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. See also: Hardness of Materials Fluorine – Crystal StructureĪ possible crystal structure of Fluorine is cubic structure. The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly.įluorine is has a hardness of approximately N/A. The most common scale for this qualitative test is Mohs scale, which is used in mineralogy. Scratch hardness is the measure of how resistant a sample is to permanent plastic deformation due to friction from a sharp object. Vickers hardness of Fluorine is approximately N/A. The Vickers hardness test method can be also used as a microhardness test method, which is mostly used for small parts, thin sections, or case depth work. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers hardness test method was developed by Robert L. In Brinell tests, a hard, spherical indenter is forced under a specific load into the surface of the metal to be tested.īrinell hardness of Fluorine is approximately N/A. Brinell hardness test is one of indentation hardness tests, that has been developed for hardness testing. In materials science, hardness is the ability to withstand surface indentation ( localized plastic deformation) and scratching. The Young’s modulus of elasticity of Fluorine is N/A. Ultimate tensile strength of Fluorine is N/A. See also: Strength of Materials Ultimate Tensile Strength of Fluorine Yield strength or yield stress is the material property defined as the stress at which a material begins to deform plastically whereas yield point is the point where nonlinear (elastic + plastic) deformation begins. Strength of a material is its ability to withstand this applied load without failure or plastic deformation.įor tensile stress, the capacity of a material or structure to withstand loads tending to elongate is known as ultimate tensile strength (UTS). In designing structures and machines, it is important to consider these factors, in order that the material selected will have adequate strength to resist applied loads or forces and retain its original shape. Strength of materials basically considers the relationship between the external loads applied to a material and the resulting deformation or change in material dimensions. In mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation.
