Question Analysis
This question tests the student's understanding of the energy requirements for different phase changes.

Key Concept Explanation
Endothermic processes require energy input, while exothermic processes release energy. Phase changes such as melting, vaporization, and sublimation are endothermic because they require energy to break intermolecular forces.

Step-by-step Solution
1. Identify the phase changes listed in the options: freezing, condensation, melting, and deposition.
2. Recall the energy requirements: melting requires energy (endoth...
