Question Analysis
This question involves distinguishing between evaporation and boiling, including their energy changes and locations of occurrence. The main focus is on understanding the differences between these two forms of vaporization.

Key Concept Explanation
Vaporization has two forms:
Evaporation: Endothermic process where liquid molecules with sufficient kinetic energy escape only from the surface of the liquid, occurring at temperatures below the boiling point.
Boiling: Endothermic process where vapor bubbles form throughout the liquid volume, occurring when the liquid’s vapor pressure equals the external atmospheric pressure (at the boiling point).

Step-by-Step Solution
1. Recall the definition of evaporation: Surface-only, below boiling point, endothermic.
2. Analyze each option:
A. Incorrect (exothermic; only at...
