The process by which a solid changes directly into a gas.
B
The process by which a liquid changes into a solid.

Verified step by step guidance1
Understand the term 'vaporization' in the context of phase changes in matter. Vaporization refers to the transition from the liquid phase to the gas phase.
Recall the different phase changes: sublimation (solid to gas), freezing (liquid to solid), condensation (gas to liquid), and vaporization (liquid to gas).
Identify that vaporization includes both evaporation (occurring at the surface below boiling point) and boiling (occurring throughout the liquid at boiling point).
Compare the given options with the definitions of phase changes to find which one matches vaporization.
Conclude that the correct description of vaporization is 'The process by which a liquid changes into a gas.'
