If the two liquids are shaken up together, there will be a net transfer of nitrous oxide from the water to the oil until the tension in each phase is the same. At that time the concentration of nitrous oxide in the oil will be about three times the concentration in the water. Under ...
Comparable to the diffusion in fluids, the movement of adatoms and adparticles is a thermally promoted process but takes place only along the plane of the interface. Therefore, mass transfer is dramatically reduced compared to diffusion within the bulk of a medium. To the best of our knowledge...
In liquids, in accordance with the nature of the thermal motion of molecules, diffusion occurs through jumps of the molecules from one temporary equilibrium position to another. Every jump takes place by imparting to the molecule an energy sufficient to break its bonds with the neighboring molecules...
5. Why do liquids diffuse faster than solids? As liquids are arranged in a way that there is a space present in between two atoms but there is no such space present in solids. So the particles present in liquid diffuse faster than solid particles. So they diffuse faster than solids....
Liquids, in turn, diffuse quicker than solids. Diffusion in chemistry is s exemplified by food dye dropped in an aqueous solution. The dye particles can be seen moving as they spread out throughout the solution. Another example is when spraying perfume the scent will be picked up as it ...
The diffusion-weighted NMR signal acquired using Pulse Field Gradient (PFG) techniques, allows for extrapolating microstructural information from porous materials and biological tissues. In recent years there has been a multiplication of diffusion models
osmosis diffusion it happens only in the liquid state. it occurs in all states of matter i.e., solids, liquids or gases. it should be movement of only water or solvent through semipermeable membrane from lower concentration to higher concentration. any type of substance that moves from higher...
True or False: The rate of diffusion is directly related to the difference in the concentration between the two liquids (inside the cell and outside the cell). The greater the difference, the greater the rate of diffusion. Acid-base catalysis may be...
smell is only in one area, however before long the smell of the air freshner has spread to other parts of the house. An everyday example of osmosis is seen in a coffee maker - water diffuses through a semipermeable membrane (the coffee filter) and takes flavor from the coffee with it....
It may also be used to measure diffusion coefficients in liquids (Shear-cell method). With analytic solution like (13.16), D can be calculated by measuring c at one position only. This is sometimes done but it is not to be expected that values derived in this way will be as reliable ...
