  2. Alligation - Wikipedia

    en.wikipedia.org/wiki/Alligation

    Alligation is an old and practical method of solving arithmetic problems related to mixtures of ingredients. There are two types of alligation: alligation medial, used to find the quantity of a mixture given the quantities of its ingredients, and alligation alternate, used to find the amount of each ingredient needed to make a mixture of a given quantity.

    The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.

  4. Mixture - Wikipedia

    en.wikipedia.org/wiki/Mixture

    mixtures have variable compositions, while compounds have a fixed, definite formula. when mixed, individual substances keep their properties in a mixture, while if they form a compound their properties can change. [10] The following table shows the main properties and examples for all possible phase combinations of the three "families" of ...

  5. Rule of mixtures - Wikipedia

    en.wikipedia.org/wiki/Rule_of_mixtures

    In materials science, a general rule of mixtures is a weighted mean used to predict various properties of a composite material. [ 1 ] [ 2 ] [ 3 ] It provides a theoretical upper- and lower-bound on properties such as the elastic modulus , ultimate tensile strength , thermal conductivity , and electrical conductivity . [ 3 ]

    mixture thereof. Note 3: The diameters of the droplets constituting the dispersed phase usually range from approximately 10 nm to 100 μm; i.e., the droplets may exceed the usual size limits for colloidal particles. Note 4: An emulsion is termed an oil/water (o/w) emulsion if the dispersed phase is an organic material and the continuous phase is

  7. Amagat's law - Wikipedia

    en.wikipedia.org/wiki/Amagat's_law

    Amagat's law states that the extensive volume V = Nv of a gas mixture is equal to the sum of volumes V i of the K component gases, if the temperature T and the pressure p remain the same: [1] [2] N v ( T , p ) = ∑ i = 1 K N i v i ( T , p ) . {\displaystyle N\,v(T,p)=\sum _{i=1}^{K}N_{i}\,v_{i}(T,p).}

  8. Mixing ratio - Wikipedia

    en.wikipedia.org/wiki/Mixing_Ratio

    In atmospheric chemistry, mixing ratio usually refers to the mole ratio r i, which is defined as the amount of a constituent n i divided by the total amount of all other constituents in a mixture: = The mole ratio is also called amount ratio. [2]

  9. Zeotropic mixture - Wikipedia

    en.wikipedia.org/wiki/Zeotropic_mixture

    Zeotropic mixtures of HFC-43-10mee and hexamethyldisiloxane can dissolve silicones and are highly compatible with polycarbonates and polyurethane. [23] They can be used to remove silicone lubricant from medical devices. [23] Zeotropic mixtures of HFC-43-10mee and isopropanol can remove ions and water from materials without porous surfaces. [23]
