Homogeneous mixture, 25. See

A solution is defined as a homogeneous mixture (see Section 1.7) of two or more substances. Gasoline, seawater, coffee, and blood plasma are all examples of solutions. The majority component of a solution is called the solvent and the minority component is called the solnte. For example, a sugar solution consists of sugar (the solute) and water (the solvent). In this book, we focus on aqueous solutions, those in which water is the solvent. Not all substances form solutions when mixed. For example, oil and water remain separate even when mixed vigorously. Whether or not a solution forms depends on the interactions between the components of the mixture. If the components attract each other, a solution forms. Sugar and water form a solution because sugar molecules and water molecules are both polar and therefore attract one another. 

Any apparatus for making homogeneous mixtures of materials used in rubber manufacture, e.g., blends of dry powders, rubber cements of solutions and rubber compounds themselves. See Internal Mixer, Open Mill. 

A change in dB/dt can be produced either by a demagnetization process or by a vibration in a non-perfectly homogeneous field. To reduce the effect of eddy currents, low-resistivity (plastic) MCs have been built (in which the sample under study is immersed in the mixture, see Fig. 6.15 showing the electrical feedthrough) and even complete plastic DR [34],... 

Macroscopically homogeneous mixture of two or more different species of polymer [3,4], Note 1 See the Gold Book, p. 312 [3]. 

Now about an LCST (lower critical solution temperature, see MT Figure 9.3). If we blend below this temperature, we can obtain a homogeneous mixture. Subsequent heating to above the LCST can resnlt in segregation the rapid cooling in an injection monlding machine does not allow to nndo this. 

Alternatively, we have shown that CO2 can be used to induce miscibility of fluorocarbon-hydrocarbon mixtures (see Figure 1), even those involving polar compounds such as methanol (2). Fluorinated organometallic complexes have been well established to have significant solubility in supercritical CO2, and their use as catalysts in this medium is well developed (10). This allows the homogeneously catalyzed reaction to be carried out in the C02-expanded homogeneous solution. 

Equation (7.1) takes no account,of any mass loss through the relief system before the peak reaction rate is reached. This is approximately true in the case where gas-only venting occurs right until the peak rate. It could be expected to be very conservative in cases where homogeneous two-phase relief occurred, for example due to inherent foaminess of the reacting mixture (see Annex 3). 

The fundamental equation for U is in agreement with the statement of the preceding section that for a homogeneous mixture of Ns substances, the state of the system can be specified by Ns + 2 properties, at least one of which is extensive. The total number of variables involved in equation 2.2-8 is 2NS + 5. Ns + 3 of these variables are extensive (U, S, V, and (nj), and Ns + 2 of the variables are intensive (T, P, /.q ). Note that except for the internal energy, these variables appear in pairs, in which one property is extensive and the other is intensive these are referred to as conjugate pairs. These pairs are given later in Table 2.1 in Section 2.7. When other kinds of work are involved, there are more than 2Ns + 5 variables in the fundamental equation for U (see Section 2.7).
