In liquids, molecules slide past each other due to their intermediate speed and the flexibility offered by the liquid state, making diffusion possible but slower than gases. Solids experience the least molecular motion, with particles primarily vibrating in place, which is why diffusion in solids is a very slow process.
May 27, 2024 · AnswerBot. ∙ 5mo ago. The rate of diffusion in liquids is slower than in gases because the particles in liquids are closer together and have stronger intermolecular forces, which hinders their ...
Both diffusion and effusion are related to the speed at which various molecules move. Diffusion in gases (mixing) is nearly instantaneous. If you release a colored gas in a container of non-colored gas, the color spreads evenly throughout the container in a second or two. In liquids, diffusion is a much slower process.
A molecule in a liquid cannot move far before colliding with another molecule, however, so the mean free path in liquids is very short, and the rate of diffusion is much slower than in gases. Fluidity: Liquids can flow, adjusting to the shape of their containers, because their molecules are free to move. This freedom of motion and their close ...
Feb 16, 2020 · For example, a small ion may diffuse more quickly through a viscous solution than a large sugar molecule. The ion has a smaller size and thus is able to move faster. The large sugar molecule moves slower because of its size. The viscosity of the solution affects both but will compound the slowed diffusion that the larger molecule undergoes.
Graham later studied the diffusion of salts into liquids and discovered that the diffusion rate in liquids is several thousand times slower than in gases. This seems relatively obvious to us today, as we know that the molecules of a gas move faster and are more spread out than molecules in a liquid. Therefore, the movement of one substance ...

What is the difference between diffusion and effusion?
Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles. 2.9: Graham's Laws of Diffusion and Effusion.
