True or False: Diffusion in solids is considered negligible because the particles are only able to vibrate around fixed positions rather than move past one another.
When a substance has reached a state where its concentration is uniform throughout a space, how is the behavior of the particles described according to the particle model?
According to the particle model, why does diffusion occur more easily in a vacuum than in air?
When a system reaches dynamic equilibrium (uniform concentration), what is the 'net movement' of the particles?
True or False: In a solid, diffusion is extremely slow because the particles lack kinetic energy and are completely stationary.
