For example, frozen nitrogen will form both the liquid phase and the vapor phase when exposed to normal temperature and pressure. Multiple phase changes can occur at once. For example, if you view the sublimation of dry ice into carbon dioxide gas, the white vapor that is observed is mostly water that is condensing from water vapor in the air into fog droplets. Phase changes aren't always clear when observing a situation.

Plasma most often forms from ionization of a gas, although if sufficient energy and enough space are available, it's presumably possible for a liquid or solid to ionize directly into a gas. Plasma: Plasma can recombine to form a gas. Gases form from the sublimation of solids, vaporization of liquids, and recombination of plasma. Gases: Gases can ionize into plasma, condense into liquids, or undergo deposition into solids. Liquids form by condensation of gases and melting of solids. Liquids: Liquids can vaporize into gases or freeze into solids. The following figure illustrates the microscopic differences. Solids form by deposition from gases or freezing of liquids. Gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases. Solids: Solids can melt into liquids or sublime into gases. Another way to list phase changes is by states of matter:
