What is the diffusion rate of solid?
Comparison – Diffusion in Solids, Liquids and Gases
| Solids | Liquid | Gases |
|---|---|---|
| Diffusion is slowest in Solids | Diffusion is fast compared to solids but slow compared to liquids | Diffusion is fastest in gases |
Why is the rate of diffusion slow in solids?
Diffusion can happen in solids as well. Solid-state diffusion is an extremely slow process. Solid particles have the lowest kinetic energy and so do not move. As a result, in the case of solids, diffusion takes a lengthy time.
How does flow rate affect diffusion?
Diffusion has time to equilibrate the concentrations between streams. The result is that slower flow rates cause the optimal linear region to occupy a small fraction of the microchannel length.
Why is the rate of diffusion higher in liquids than in solids?
in the liquid state, particles are tightly packed. in the liquid state, particles move freely as compared to solids. in solid state, particles have least force of attraction between the particles. in solid state, particles cannot be compressed easily.
What is the rate of diffusion of solid liquid and gas?
THE RATE OF DIFFUSION IS FAST IN GAS , AND THEN IN LIQUID AND SLOWER IN SOLID. GAS DIFFUSE VERY FAST BECAUSE THE INTERMOLECULAR SPACE BETWEEN THE PARTICLES ARE VERY FAR AWAY FROM EACH OTHER.
Is diffusion faster through a liquid or a solid?
Generally, gases diffuse much faster than liquids, and liquids much faster than solids. Diffusion may take place through a semipermeable membrane, which allows some, but not all, substances to pass.
Why is diffusion faster in liquids than solids?
The rate of diffusion of liquids higher than that of solids because liquids have higher inter-particle space than solids. This leads to higher fluidity than solids as the particles in a liquid are not as closely packed as in case of solids.
What is diffusion in flow rate?
Diffusion: Diffusion refers to the transport of substance against a concentration gradient. Mass transfer: movement of mass from one place to another. Diffusion: movement of mass from region of high concentration to low. concentration. J = -D.
Why is diffusion faster in liquid?
When the temperature is changed, it occurs quicker. Liquid provides less room to move so that collisions between the molecules are more frequent and the diffusion rate is slower. For gases there is more space. As a consequence, less collisions are creating an improved diffusion rate between molecules.
