Show answer Hide answer
Answer
Particles spread out more at each step.

Explanation

Stage Particle arrangement
Ice (solid) Tightly packed, fixed positions.
Water (liquid) A little farther apart, moving around.
Water vapour (gas) Widely spaced, free to move everywhere.
As ice melts and vaporises, particles move from tightly packed to free and widely spaced.
