Question

unit review - matter and change
which sample represents a suspension?
tyndall filtered
sample 1 yes yes
sample 2 no no
sample 3 yes no
sample 1
sample 3
sample 2

Explanation:

Suspensions exhibit the Tyndall effect (scatter light, so "Yes" for Tyndall) because their particles are large enough to block light. Additionally, suspension particles are large enough to be trapped by a filter, so they cannot pass through, meaning "No" for being filtered. Matching these properties to the samples: Sample 3 has both "Yes" for Tyndall and "No" for filtered.

Answer:

sample 3
