Some solids diffuse in liquids but not in gases some solids diffuse in gases but not in liquids why brainly
Answers
The diffusion of solids in gases or liquids is dependent on several chemical and physical properties of the solid or gas under observation. Diffusion is the movement of a substance from a region of higher concentration into a region of lower concentration.
The reason behind the diffusion of gases into solids is the physical and chemical structure of the solid. If the solid has large gaps in between each atom, there is enough space for the gaseous atoms to slip in between. Similarly, if the solid has a high affinity to gaseous atoms and is able to bond chemically with the gas, diffusion will occur.
For a solid to diffuse into a gas, it must sublime or should be able to decompose into gaseous atoms or particles. If this happens, the solid particles will bind with the gaseous particles to form a uniform mixture.
This is how certain solids and gases diffuse into each other.
Answer:
generally it depends on particles size. ... there is less intermolecular space between particles of water than in air so particles of solid and liquid are packed tightly. and some solids diffuse in air because they need more intermolecular space that air can provide but water can not
