M1 · 1 mark · States that particles in a liquid can move around each other.
M2 · 1 mark · States that particles in a solid are fixed in place or only vibrate about fixed positions.
Worked solution
Particles in liquids can move past each other because they are not fixed in place, allowing liquids to flow. In solids, particles are fixed and can only vibrate, so solids cannot flow.
