Question Analysis
This question evaluates the student's understanding of the behavior of temperature during a phase change, specifically vaporization.

Key Concept Explanation
During a phase change, the temperature of a substance remains constant as the added heat is used to break intermolecular forces rather than increasing the kinetic energy of the molecules.

Step-by-step Solution
1. Identify the phase change: liquid to gas (vaporization).
2. Recall the key concept: temperature remains constant during a phase change due to the latent heat of vaporization.
3. Match the correct answer: th...
