MYP Chemistry Topic 1.3 Diffusion Questionbank

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.

The particles move in a specific pattern to maintain the balance

The particles continue to move randomly but there is no net movement

The particles move only toward the walls of the container

The particles stop moving entirely

Gravity does not exist in a vacuum to cause sedimentation

Particles have more energy in a vacuum

The concentration gradient is always steeper in a vacuum

There are no other particles to collide with and slow down the spreading

Movement only occurs at the boundaries of the container

Maximum movement in one direction

Particles stop moving entirely
