Why is diffusion faster in gas

You do not have to mix the gases by waving your arms around - they mix on their own. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster. However, a smell does not travel this fast. This is because its particles collide with each other and with particles of air very frequently.

They change direction randomly when they collide, so it takes much longer to travel from one place to another. Their random motion because of collisions is called Brownian motion. Solutions :. Samar Arzoo. Related Doubts Explain why, the diffusion of a solid in another solid is a very slow process.

Diffusion is the process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration.

Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices. At approximately what distance from the ammonia moistened plug does this occur? Effusion can be defined as the process by which a gas escapes through a pinhole into a vacuum.

Both A and B are in the same container at the same temperature, and therefore will have the same kinetic energy:. Skip to content Chapter 9. Example 2 Effusion Time Calculations It takes s for 4. Answer: 32 h. Use of Diffusion for Nuclear Energy Applications: Uranium Enrichment Gaseous diffusion has been used to produce enriched uranium for use in nuclear power plants and weapons.

Figure 4. In a diffuser, gaseous UF 6 is pumped through a porous barrier, which partially separates UF 6 from UF 6 The UF 6 must pass through many large diffuser units to achieve sufficient enrichment in U. Explain why the numbers of molecules are not identical in the left- and right-hand bulbs shown in the center illustration of Figure 1.
