Question

Define diffusion . Do solids diffuse into each other ? if yes the explain with example Long answer type Question​

Answer 1

Answer:

diffusion in solids is a very slow process because the particles in solids do not move from their fixed positions hence they only vibrate. Example:::::::if two metal blocks r bound together tightly & kept undisturbed for a few yrs then the particles of one metal r found to have diffused into the other metal.

The spreading out and mixing of a substance with another substance due to the motion of its particles is called diffusion. Diffusion is the property of matter which is based on the motion of its particles. Diffusion occurs in gases, liquids and solids. Diffusion is fastest in gases and slowest in solids.

This model describes how diffusion occurs between two adjacent solids. One of the possible net effects of diffusion is that atoms move from regions of high concentration of one element to regions with low concentration, until the concentration is equal throughout the sample.
