What happens if atoms lose energy during a change of state?

The atoms are pushed apart by repulsive forces and become less organized.
The atoms are pulled together by attractive forces and become less organized.

Answer 1

The atoms are pulled together by attractive forces and become more organized.

When a substance loses energy (cooling), particle motion decreases, allowing attractive forces to pull particles closer. That leads to denser, more ordered states (gas → liquid → solid).
