States of Matter and Sublimation

Vocabulary flashcards reviewing states of matter, standard room temperature baseline, sublimation, and reverse sublimation based on the lecture notes.

Three states of matter

The three physical forms in which a substance can exist: solid, liquid, and gas, depending on temperature.

Standard reference temperature for state of matter

The room temperature baseline set at $20^\circ\text{C}$ used to characterize whether a substance is solid, liquid, or gas.

Sublimation

The phase transition in which a substance converts directly from a solid state into a gaseous state, observed in substances like iodine, dry ice, and ice.

Dry ice

The common name for solid carbon dioxide, which directly sublimates into a gas.

Reverse sublimation

The process where a gas transitions directly into a solid deposit, as exemplified by hail and snow.
