Phases are sometimes confused with states of matter, but there are significant differences. States of matter refers to the differences between gases, liquids, solids, plasma, etc. If there are two regions in a chemical system that are in different states of matter, then they must be different phases. However, the reverse is not true -- a system can have multiple phases which are in equilibrium with each other and also in the same state of matter. This difference is especially important when considering the Gibbs' phase rule, which governs the number of allowed phases. | Phases are sometimes confused with states of matter, but there are significant differences.

Mixtures can have multiple phases, which often happen when two immiscible substances dissolve into one another in small amounts. For example, a mixture might be composed of an oil phase (95% oil, 5% water) and a water phase (95% water, 5% oil). | Mixtures can have multiple phases, which often happen when two immiscible substances dissolve into one another in small amounts.

Polymorphism is the ability of a solid to exist in more than one crystal form. For example, water ice is ordinarily found in the hexagonal form Ice Ih, but can also exist as the cubic ice Ic, the rhombohedral ice II, and many other forms. | Polymorphism is the ability of a solid to exist in more than one crystal form.

Amorphous phases are also possible with the same molecule, such as amorphous ice. In this case, the phenomenon is known as polyamorphism. | Amorphous phases are also possible with the same molecule, such as amorphous ice. In this case, the phenomenon is known as polyamorphism. | ||

For pure chemical elements, polymorphism is known as allotropy. For example, diamond, graphite, and fullerenes are different allotropes of carbon. | For pure chemical elements, polymorphism is known as allotropy.
