which of the following situations provides evidence that the particles for matter in its solid state stay closely packed and rigid, but the particles in its liquid state flow freely?

Question

ice cubes sliding across a solid surface
water boiling into steam
ice melting into water
rain forming a puddle on the ground

Answer 1

The situation that provides evidence that the particles for matter in its solid state stay closely packed and rigid, but the particles in its liquid state flow freely is ice melting into water.

When ice (solid) melts into water (liquid), it demonstrates how the rigid structure of ice with tightly packed particles changes to a more fluid state where the particles can move around each other, indicating that they are no longer held in a fixed position.
