What is the difference between vaporization and evaporation?

• Vaporization occurs at the boiling point, while evaporation occurs at any temperature.

• Both occur only at the boiling point.

• Both occur only at room temperature.

• Evaporation occurs at the boiling point, while vaporization occurs at any temperature.

What is the difference between vaporization and evaporation?

• Vaporization occurs at the surface of the liquid, while evaporation occurs throughout the liquid.

• Both occur throughout the liquid.

• Both occur only at the surface.

• Evaporation occurs at the surface of the liquid, while vaporization occurs throughout the liquid.
