Chemistry- Diffusion Flashcards
What is meant by equilibrium?
Evenly spread
What is meant by a low concentration?
An area that contains few particles.
Big particles will diffuse more ______ than smaller particles.
slowly
High temperatures cause diffusion to happen…
faster
What is the definition of diffusion?
The net movement of particles from a high concentration to a low concentration until they are at equilibrium.
Low temperatures cause diffusion to happen…
slowly
What is meant by a high concentration?
An area that contains many particles.
Why can diffusion not happen in solids?
Because the particles in a solid are fixed in position.
Substances in which states can diffuse?
Liquids and gases - because their particles can move around.
What is meant by the net movement of particles?
The overall direction that particles move in.
What can affect the speed (rate) of diffusion?
Temperature
Particle size
The state of the substance
