Diffusion is slowest in solid particles than in particles of liquid and gases because
solid particles have more kinetic energy than the particles of liquid and gases
solid particles have less kinetic energy than the particles of liqiud and gases
solid particles have less restriction in their movement than liquid and gas particles
the particles in solids are far apart and the cohesive forces between them are negligible
Explanation
Diffusion is faster in gases owing to their higher kinetic energy i.e increase in kinetic energy of molecules leads to increase in rate of diffusion.
