Show answer
Both can flow (are fluids); in liquids particles are close together but not in a regular arrangement as in solids.
Also accept: Both flow; both have no definite shape; particles close but irregular for liquids
Common mistakes: Saying particles in liquids are far apart

B2 · 1 mark · Describes that particles in a liquid are close together but not in a regular arrangement (unlike solids).
Worked solution
One property is that both liquids and gases can flow. In a liquid, the particles are close together like in a solid, but they are not arranged regularly—they move around randomly.
