Diffusion in solid phase is possible.
Diffusion is slower in agar than in water because agar is a gelatinous substance that contains solid particles which obstruct the free movement of molecules. This impedes the diffusion of molecules through the agar compared to the unrestricted movement in water, which lacks solid particles.
Different tissues have varying permeability to molecules, which impacts the rate of diffusion. Tissues with higher permeability, such as lungs or intestines, allow for faster diffusion due to more open pathways for molecules to pass through. In contrast, tissues with lower permeability, like skin or brain tissue, experience slower diffusion rates as molecules encounter barriers to passage.
Facilitated diffusion moves molecules through cell membranes passively.
This movement is called diffusion, where molecules move from an area of higher concentration to an area of lower concentration in order to achieve equilibrium. The process is driven by the random motion of molecules and does not require energy input.
Diffusion is determined by the concentration gradient, temperature, and the size of the molecules. The greater the difference in concentration, the higher the temperature, and the smaller the molecules, the faster diffusion will occur.
What kind of diffusion? If it is diffusion of molecules then gas would be the right platform
Molecules in a solid are stuck in a matrix or crystal and basically don't move. No motion, no diffusion.
Diffusion is slower in agar than in water because agar is a gelatinous substance that contains solid particles which obstruct the free movement of molecules. This impedes the diffusion of molecules through the agar compared to the unrestricted movement in water, which lacks solid particles.
The intermolecular forces holding gas molecules together are not very strong and thus the molecules are free to move around freely. This allows diffusion. The intermolecular forces holding molecules of a solid together are rather strong, and the molecules thus cannot move very freely. This prevents diffusion.
No, molecules naturally move from areas of high concentration to low concentration in a process known as diffusion. This movement occurs to reach an equilibrium where molecules are evenly distributed.
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. It occurs in liquids, gases, and solids, as long as there is a concentration gradient present.
Different tissues have varying permeability to molecules, which impacts the rate of diffusion. Tissues with higher permeability, such as lungs or intestines, allow for faster diffusion due to more open pathways for molecules to pass through. In contrast, tissues with lower permeability, like skin or brain tissue, experience slower diffusion rates as molecules encounter barriers to passage.
Facilitated diffusion moves molecules through cell membranes passively.
In general, larger molecules diffuse more slowly than smaller molecules because they have a larger molecular weight and therefore experience more resistance from the surrounding medium as they move. This is due to the fact that larger molecules have a lower diffusion coefficient and therefore diffuse at a slower rate. Additionally, larger molecules may also be more prone to interacting with other molecules in their surroundings, further slowing down their diffusion.
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Diffusion is not a substance. It is a physical process. Diffusion is the process where there is a movement of molecules from where they are abundant to where they are scarce. A more technical definition would be: Diffusion is a process in which molecules move from a region of higher concentration to a region of lower concentration.
