Solid homogeneous

Whatever application method is used, there is always a heating step. When p.v.c. plastisol is heated to over 100°C the p.v.c. resin which is suspended in plasticiser stabiliser etc. starts to dissolve in the plasticisers. When solution is complete the system is cooled to room temperature and a solid homogeneous coating results. 

Example butter, an emulsion of water in butterfat. solid solution A solid homogeneous mixture of two or more substances. 

Nucleation can occur within any given solid (homogeneous nucleation) or be induced by any outside factor (heterogeneous), including the presence of a foreign soUd. 

The purpose of this chapter is to outline the simplest methods of arriving at a description of the distribution of species in mixtures of liquids, gases and solids. Homogeneous equilibrium deals with single phase systems, such as electrolyte solutions (e.g., seawater) or gas mixtures (e.g., a volcanic gas). Heterogeneous equilibrium involves coexisting gaseous, liquid and solid phases. 

SN1 and reactions Two varieties of nucleophilic substitution, with unimolecular and bimolecular ratedetermining stages, respectively, sol A colloidal dispersion of solid particles in a liquid, solid A rigid form of matter that maintains the same shape whatever the shape of its container, solid emulsion A colloidal dispersion of a liquid in a solid. Example butter, an emulsion of water in butterfat. solid solution A solid homogeneous mixture of two or more substances. 

Aromatic aldehydes (10 mmol) and trimethylorthoformate (20 mmol) was added to a mixture of sulfonamide (10 mmol), finely powdered calcium carbonate (9 g) and K-10 clay (2 g). The solid homogenized mixture was placed in a modified reaction tube which was connected to a removable cold finger and sample collector to trap the ensuing methanol and methyl formate. The reaction tube is inserted into Maxidigest MX 350 (Prolabo) microwave reactor equipped with a rotational mixing system. After irradiation for a specified period, the contents were cooled to room temperature and mixed thoroughly with ethyl acetate (2 x 20 mL). The solid inorganic material was filtered off and solvent was evaporated to afford tlie residue which was crystallized from the mixture of hexane and ethyl acetate.

Crystal—A solid, homogeneous body composed of a single element or compound having a fixed and regular internal atomic arrangement that may be expressed by external planar faces. 

Introduction Aggregates are those parts of the concrete that constitute the bulk of the finished product. They comprise 60-80% of the volume of the concrete, and have to be so graded that the whole mass of concrete acts as a relatively solid, homogenous, dense combination, with the smaller sizes acting as inert filler of the voids that exist between the larger particles. 

The number of transfer units for each mechanism can be estimated from known parameters and mass transfer correlations (4). For example, for a column with particles 0.01 cm in diameter, a superficial velocity of 0.01 cm/sec, and a solute bulk diffusivity of 7 x 10-7 cm2/sec, the estimated number of transfer units in a packed bed of length L for the four mechanisms, axial dispersion, external fluid film mass transfer, pore diffusion, and solid homogeneous particle diffusion,are...

This holds for any system, gaseous, liquid, or solid, homogeneous or heterogeneous. 

We must, in fact, first postulate two things (i) that the temperature is supposed to be maintained constant, and (2) that the reaction under consideration can proceed without a volume change Now scarcely any reaction takes place without a volume change, but m condensed systems, as van t Hoff called them, that is in systems either liquid or solid (homogeneous or heterogeneous) we can imagine the reaction to occur practically without a volume change... 

Matter is composed of atoms, which move through empty space. Atoms are solid, homogeneous, indestructible, and indivisible. Different kinds of atoms have different sizes and shapes. 

I According to Democritus, atoms are solid, homogeneous, and indivisible.

The theoretical analysis presented above assumes a solid homogeneous spherical dielectric particle, e.g., a polystyrene bead. Biological cells are neither perfect spheres nor completely homogenous dielectrics. However, their DEP properties can be... 

These unexpected results are in a sense confirmed by the fact that Eq. (109a) is indeed well verified by the numerical data for solid spheres. Similar calculations were conducted with spheres with a uniform porosity. Their solid fraction (j)] was set to equal to 0.25, 0.50, and 0.75, yielding ao/cj) = 2.6, 2.5, and 2.05, respectively. In this situation, Gq can be estimated by replacing the porous spheres with solid homogeneous ones with conductivity Cj = aac. Their volume fraction in...
