Which Gas Has Highest Diffusion Rate? As per Graham’s law, the rate of effusion or diffusion is inversely proportional to the square root of its molecular weight. Consequently, the gas with the least molecular weight effuses the fastest hence, helium gas has a higher rate of diffusion compared to nitrogen or oxygen. Why do gases
How Do You Explain Diffusion? Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and
How Does Diffusion Occur In Liquids And Gases? Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances
What Is An Example Of Diffusion In Everyday Life? Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored. What are 2 examples of
Is Diffusion Coefficient Dependent On Temperature? The diffusion coefficient is a physical constant dependent on molecule size and other properties of the diffusing substance as well as on temperature and pressure. How does diffusion coefficient change with temperature? The coefficient of diffusion increases gradually as the temperature of the air increases. The activation energy was
What Gas Diffuses The Fastest? The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium. Which gas diffuses rapidly Why? At any given temperature, small, light molecules
