Question

what happens to the particles in water as the water is heated and turns to vapor? the particles move more quickly. the particles are destroyed. the particles become smaller. the particles stop moving.

Explanation:

When water is heated and turns to vapor, it is a physical change. According to the kinetic - molecular theory, heat energy increases the kinetic energy of particles, making them move more quickly. Particles are not destroyed, do not become smaller, and do not stop moving during this phase change.

Answer:

The particles move more quickly.
