Question Analysis
This question involves identifying correct statements about exothermic phase changes. The main focus is on classifying phase changes by their energy direction and linking them to particle order.

Key Concept Explanation
Exothermic phase changes release thermal energy to the surroundings. They involve transitions to a more ordered state (gas → liquid → solid), where intermolecular forces strengthen.
Examples include freezing, condensation, and deposition.
Endothermic changes (melting, vaporization, sublimation) absorb energy and transition to less ordered states.

Step-by-Step Solution
1. Recall the definition of exothermic phase changes: Release energy, more ordered state.
2. Analyze each option:
A. Incorrect (exothermic = more ordered state).
B. Incorrect (exothermic = release energy, ...
