A sample of liquid is heated until it is boiling. Which of the following statements correctly describes how boiling differs from evaporation?
Boiling takes place only at the surface of the liquid, whereas evaporation takes place throughout the liquid.
Boiling occurs at any temperature, whereas evaporation only occurs at a single specific temperature.
Boiling occurs throughout the liquid and at a specific temperature, whereas evaporation occurs only at the surface and at any temperature.
During boiling, only the fastest-moving molecules at the surface can escape, whereas during evaporation, any molecule can escape from any part of the liquid.
