Question

1. Diffusion Of Solids

Answer 1

Explanation:

Diffusion is a process generally visible in gases and the liquids . Diffusion in solids has been a matter of research for many years . But now it has been proved that the diffusion in solids takes place . It is a extremely slow process and hence is not visible and observable . But solids do diffuse . Due to highly dense and strong packing of molecules in the solids , the diffusion takes a very long time ( many years) to diffuse as compared to liquids and gases which hardly take few minutes
