Diffusion: a review draft
Citations are structural links to source locations. They do not prove that the wording is correct.
Overview
Not selected
Diffusion is the net movement of particles from a more concentrated region to a less concentrated region.
Factors that change the rate
Not selected
A higher temperature usually increases the rate because particles have more kinetic energy.
A steeper concentration gradient also increases the rate.
Check yourself
Not selected
Explain why diffusion does not require a partially permeable membrane.
source 1: Synthetic diffusion notes
Diffusion is the net movement of particles from a region where they are more concentrated to a region where they are less concentrated.
Linked source location — not a correctness or mastery claim.
Coverage: partial
The source supports the main definition, but one wording choice still needs learner review.
Needs more source detail: Which details need checking?
This label describes structural coverage only; it is not proof of completeness.
Check this wording
Check that ‘usually increases’ is kept; the source does not say ‘always’.
