2. Tape diagram - Wikipedia

   en.wikipedia.org/wiki/Tape_diagram

   A tape diagram is a rectangular visual model resembling a piece of tape, that is used to assist with the calculation of ratios and addition, subtraction, and commonly multiplication. It is also known as a divided bar model, fraction strip, length model or strip diagram.

3. Elastic properties of the elements (data page) - Wikipedia

   en.wikipedia.org/wiki/Elastic_properties_of_the...

   Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

4. Mass-to-charge ratio - Wikipedia

   en.wikipedia.org/wiki/Mass-to-charge_ratio

   The mass-to-charge ratio (m/Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles , e.g. in electron optics and ion optics .

5. Particle-size distribution - Wikipedia

   en.wikipedia.org/wiki/Particle-size_distribution

   Cascade impactors – particulate matter is withdrawn isokinetically from a source and segregated by size in a cascade impactor at the sampling point exhaust conditions of temperature, pressure, etc. Cascade impactors use the principle of inertial separation to size segregate particle samples from a particle laden gas stream. The mass of each ...

6. Ratio - Wikipedia

   en.wikipedia.org/wiki/Ratio

   The ratio of numbers A and B can be expressed as: [6] the ratio of A to B; A:B; A is to B (when followed by "as C is to D "; see below) a fraction with A as numerator and B as denominator that represents the quotient (i.e., A divided by B, or). This can be expressed as a simple or a decimal fraction, or as a percentage, etc. [7]

7. Phase diagram - Wikipedia

   en.wikipedia.org/wiki/Phase_diagram

   It is possible to envision three-dimensional (3D) graphs showing three thermodynamic quantities. [12] [13] For example, for a single component, a 3D Cartesian coordinate type graph can show temperature (T) on one axis, pressure (p) on a second axis, and specific volume (v) on a third. Such a 3D graph is sometimes called a p–v–T diagram. The ...
