WebCannabis dabs can also be found in a slightly liquid form, referred to as sap. Budder, oil, and wax are softer, more opaque versions, each earning their name from the consistency of … WebApr 27, 2024 · Diffusion Definition. Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states.

Webmixture. We further assume that the solubility of B in liquid A is negligible. At the top of the tube (at z = z2) a stream of gas mixture A-B of concen-tration A2x flows past slowly; thereby the mole fraction of A at the top of the column is maintained at A2. The entire system is presumed to be held atx constant temperature and pressure. WebMathematical description of equimolar counterdiffusion [ edit] However, if a mixture is not of a pure concentration but consists of two species; then it is a binary flow, and the two flows must balance each other. This type of diffusion is referred to as equimolar counterdiffusion, and the two species, A and B, are in combination with each other. Web(2.2) gives -DAB = (CA/ Z )= - (-) DBA CB /Z Substituting eq. (2.5) in eq. (2.7) and on simplification DAB = DBA This shows that the diffusivity is same for diffusion of A in B or B in A. 2.4 Steady State molecular diffusion in Fluids In the above discussion, we considered Ficks law for diffusion in a stationary fluid, i.e. there is no ... shuck your own oysters near me
