Sublimation is a process where a substance transitions from a solid state directly to a gas state, bypassing the liquid phase. This phenomenon occurs under specific conditions of pressure and temperature. For example, dry ice (solid carbon dioxide) sublimates at temperatures above -78.5 °C and turns into gaseous carbon dioxide without becoming a liquid.

In contrast, the other options mentioned in your question represent different phase changes:

1. **Gas to Solid**: This process is known as deposition, where gas particles lose energy to become solid without passing through a liquid state.
2. **Solid to Liquid**: This is called melting, where a solid absorbs heat energy and transitions into the liquid phase.
3. **Liquid to Gas**: This process is known as evaporation (or boiling when it occurs throughout the liquid) where a liquid absorbs sufficient heat energy to become a gas.

Thus, in the context of your question, the correct response is that sublimation specifically refers to the process where a solid changes directly into a gas.
