Question

select the text from the paragraph that best helps you understand that sublimation means a physical process in which a solid changes directly to a gas. there may be more than one correct choice.

a phase transition occurs when a substance is transformed from one state of matter into another due to changes in temperature or pressure. some phase transitions, like melting, freezing, evaporation, and condensation, are commonly observed in everyday life. for example, when water freezes to form ice, it undergoes a phase transition from a liquid state to a solid state; and when it evaporates, it undergoes a phase transition from liquid to gas. other phase transitions, however, are less common. one such change is sublimation, a process exemplified by the behavior of dry ice—frozen carbon dioxide commonly used to keep packaged items cold and dry during shipping. when dry ice is left at room temperature, the solid carbon dioxide changes to carbon dioxide gas without melting into a liquid first.

Explanation:

The text "the solid carbon dioxide changes to carbon dioxide gas without melting into a liquid first" directly describes a solid (dry ice - solid carbon dioxide) changing to a gas (carbon dioxide gas) without going through the liquid state. This matches the definition of sublimation (a solid changes directly to a gas).

Answer:

the solid carbon dioxide changes to carbon dioxide gas without melting into a liquid first
