Question Analysis
This question involves understanding the relationship between phase changes and intermolecular forces. The main focus is on recognizing that all phase transitions require a change in the strength of interactions between particles.

Key Concept Explanation
Phase changes involve energy changes that alter the balance between particle kinetic energy and intermolecular forces.
Endothermic processes (melting, sublimation, vaporization) require energy to overcome intermolecular forces, while exothermic processes (freezing, deposition, condensation) involve particles coming closer together, strengthening intermolecular forces.

Step-by-Step Solution
1. Analyze the relationship between phase changes and intermolecular forces:
Melting: Overcome some intermolecular forces (solid → liquid)
Sublimation: Overcome all intermolecular forces (solid → gas)
