Marbles, mixing

We could explain the results of this experiment die way we did before die final distribution is clearly much more probable than the initial distribution. There is, however, another useful way of looking at this process. The system has gone from a highly ordered state (all the H2 molecules on the left, all the N2 molecules on the right) to a more disordered, or random, state in which the molecules are distributed evenly between the two bulbs. The same situation holds when marbles rather than molecules are mixed (Figure 17.3). In general, nature tends to move spontaneously from more ordered to more random states. 

These two possibilities are attractive because they are simple—one factor alone is held responsible for the weight difference. We must be prepared, however, for disappointment. There is the third possibility that neither of these proposals, A or B, accounts for the properties of gases. After all, neither A nor B applies to the beans and marbles example. The bag probably wouldn t contain the same number of beans as marbles (as in B) but, in addition, beans and marbles don t weigh the same (as in A). We need more information to decide if either proposal A or B applies to gases. More information is obtained by observing how some gases behave when mixed. 

Methyl fluoroacetate.1 Methyl chloroacetate (108-5 g., 1 mol.) and neutral anhydrous potassium fluoride (70 g., 1-2 mol.) are mixed and heated (with glass marbles) in an inclined rotating autoclave at a... 

A series of slurries of high solids, dispersed ground calcium carbonate were prepared. Firstly, a sample of Carrara marble was ground without dispersant to a mean size of 0.5 fim. This was then filtered to a solids level of 76% (volume fraction 46%), before being thoroughly mixed with the required dose of sodium polyacrylate dispersant and adjusted to a constant solids level of 70%. Doses ranged from zero to 25mgg (2.5%) of calcium carbonate. Samples were then left for two days to reach a steady-state adsorption level. After this they were sheared and their viscosity (Brookfield RV, 100 rpm, spindle 3) was measured. 

A basic copper chlorate is formed when soln. of potassium chlorate acidified with sulphuric acid are electrolyzed with an alternating current between copper electrodes (L. Rossi) 83 when the hydrate is heated above 100° (A. Wachter) when a soln. of copper chlorate be mixed with pieces of marble or urea, and heated in a sealed tube to 130° (L. Bourgeois) when the hydroxides of the alkalies or alkaline earths act on cupric chlorate soln., or copper hydroxide acts on soln. of potassium chlorate (A. Brochet) when hydrated cupric oxide or cupric hydroxide acts on cupric chlorate soln. (P. Sabatier) or when potassium chlorate acts on cupric acetate soln. (A. Casselmann), basic cupric chlorate is obtained. The basic chlorate forms bluish-green monoclinic prisms of sp. gr. 3 55 and composition 4Cu0.C1205.3H20, that is, Cu(C103)2.3Cu(0H)2, which A. Werner considers to be hexahydroxyl cupric chlorate ... 

Take 1 libra of native sulphur, 2 libra of charcoal of linden or willow, 6 libra of sal petrosum which are all three well mixed on a marble stone. Afterwards place the pow-... 

A mixture is a combination of several different things. For example, if you mix red marbles and blue marbles you have a mixture of different colored marbles. To separate this mixture of marbles you can pick out all the red marbles and place them in a separate pile. 

A few words of explanation are not useless in order to understand this formalism. As a consequence of mixing, the medium is assumed to have a lamellar structure and n is a unit vector which remains normal to the material slices undergoing deformations in the velocity field, n n denotes a dyadic product (the dyadic product of vectors a and b is the tensor a.jbj) and 13 n n denotes the scalar product of the two tensors (the scalar product of tensors i = Tij and W = is the scalar quantity T W = E Z T j wji)- Assume that we start with two miscible fluids A J and B (having for instance different colors). Upon mixing, we obtain a lamellar marbled structure characterized by a striation thickness 6 and a specific "interfacial" area av. If the fluid is incompressible, avS = 1. Then,by application of (7-1)... 

Jazzy, marbled, or tortoiseshell effects can be produced in moulded components by using starting materials in a selection of different colours, or by using two or more masterbatches. Such effects are attractive for certain purposes but it is important to remember that when preparing the melt intensive mixing must not take place machines are made specially to ensure that the pattern required in a moulding can be reproduced precisely. 

Prepare the amount ofcolor reagent you need—3 ml to he added to each tube containing 2 ml of carbamyl aspartate standard or enzyme assay mixture after addition of perchloric acid. Add 3 ml to each assay and standard tube and mix thoroughly. Cap the tubes with marbles or parafilm, carver them with aluminum foil, and store in a dark place at room temperature until the next lab period (15-48 hr is satisfactory).
