Explanation:

Vaporization is a phase change from liquid to gas. In a liquid (before vaporization), particles are close together, with some space between them, and move past each other. After vaporization (in gas), particles are far apart, move freely and rapidly, and have large spaces between them.

• Before (Liquid): Draw small circles (particles) relatively close, some touching or near each other, arranged with moderate density (e.g., 5 - 7 particles in the left box, clustered but not too tightly).
• After (Gas): Draw the same number of particles (to show conservation of matter) but spread out widely, with large gaps between them (e.g., 5 - 7 particles in the right box, spaced far apart, moving in different directions).

Answer:

• Left Box (Before Vaporization, Liquid): Draw 5–7 small, closely - spaced circles (representing liquid particles, with moderate intermolecular attraction, moving past each other).
• Right Box (After Vaporization, Gas): Draw the same number of circles, widely spaced with large gaps (representing gas particles, with weak intermolecular attraction, moving freely and rapidly).
