Question Analysis
This question assesses the student's ability to determine phase changes based on given temperature and pressure conditions.

Key Concept Explanation
Melting is the phase change where a substance transitions from a solid to a liquid. It occurs when the temperature rises above the melting point at a given pressure.

Step-by-step Solution
1. Identify the initial conditions: T = 35°C, P = 1 atm.
2. Identify the final conditions: T = 45°C, P = 1 atm.
3. Determine the melting point: 40°C at 1 atm.
4. As the temperature increases from 35°C to 45°C...
