Understand the definition of sublimation: it is the phase change where a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase.
Recall the common phase changes: melting (solid to liquid), vaporization (liquid to gas), condensation (gas to liquid), freezing (liquid to solid), deposition (gas to solid), and sublimation (solid to gas).
Identify that sublimation is the opposite of deposition, which is gas to solid.
Match the given options to the definitions: 'Gas to solid' corresponds to deposition, 'Solid to liquid' corresponds to melting, 'Liquid to gas' corresponds to vaporization.
Conclude that the correct phase change for sublimation is 'Solid to gas' as it fits the definition of sublimation.
