While studying science, you might hear about the term ‘matter’. Anything that occupies space or, in other words, has volume and mass (weight) is considered as matter. The Phase of matter and state of matter has a similar meaning, but they are used in several different contexts. The Phase of matter has uniformly distributed properties, but the state of matter may vary in the uniformity of composition and chemical and physical properties.

Phase of Matter vs State of Matter
The main difference between the phase of matter and state of matter is that in the phase of matter, the composition and properties of the substance or matter are uniforms, and it changes from one phase to another by following some processes or procedures. On the contrary, the state of matter is the state or the form that matter takes due to external forces, including temperature and pressure.
The Phase of the matter is defined as a change in the phase of matter from one form to another. The various process is used to bring physical and chemical change in the matter which eventually affects its phase. The phases of matter are changed either by removing or adding energy from a matter that eventually causes molecular motion.
State of the matter is considered as the particular state of matter in some defined measures of temperature and pressure. The distribution of properties in a state of matter can be varied. One state of matter can have various phases, and there could be an uneven distribution of properties.
Comparison Table Between Phase of Matter and State of Matter
|Parameters of Comparison||Phase of Matter||State of Matter|
|Meaning||The phase of matter in the form of matter in which the properties and distributed uniformly||The State of matter is defined as a form of matter in fixed external factors like temperature and pressure|
|Properties||It has a uniform distribution of properties.||It may or may not possess the uniform distribution of the properties.|
|Phase||The phase of matter has one constant phase.||It may have several phases.|
|Transition||The uniformity of substance will not get affected by a change in phase.||The uniformity of the substance or matter may or may not change with change in state.|
|Example||Liquid state, solid-state, plasma state, gaseous state||Gaseous phase, liquid phase, plasma phase, solid phase.|
What is Phase of Matter?
The phase of matter is a scientific term in which matter posses uniform physical and chemical properties. Usually, there are four phases of matter, including gas, solid, plasma, and liquid as well. All these phases acquire uniform chemical and physical properties like the index of refraction, the composition of chemicals, density, etc.
The difference in the various phases of matter mainly depends on the motion and arrangement of particles like atoms, ions, and molecules. One phase can be changed to another by changing various measures, and this phenomenon is called a phase transition. Examples of phase transition include freezing, condensation, melting, etc.
What is State of Matter?
The state of matter varies from a change in external factors like temperature and pressure. In certain conditions of temperature and pressure, a matter or a substance can possess four states-
- Gaseous State
- Liquid State
- Plasma State
- Solid State
In a state of matter, it is not compulsory that the matter or the substance possess uniform properties (chemical and physical). Hence, one state of matter can have more several phases. You can change the state of the substance by changing the temperature because the temperature can directly impact the internal energy of the matter, which consequently changes the kinetic energy and results in a change in the state of that substance.
Main Differences Between Phase of Matter and State of Matter
- The phase of matter is defined as the form of a substance in which the properties are distributed uniformly. On the other hand, the state of matter is defined as the form or state acquire by the substance at a particular or given condition of temperature and pressure. Although both of these terms are categorized into similar forms, gas, plasma, liquid, and solid
- The phase of matter and state of matter both explained the form that a matter or a substance possesses under various conditions. The phase of matter has uniformity in the properties, or in other words, the chemical and physical properties of the substance or matter are the same and uniform at every point of the matter, but on the contrary, the properties in the state of matter vary in the uniformity of properties.
- The phase of matter can acquire one phase at certain conditions or external measures and factors. The state of matter can possess various phases. For instance, in the room temperature and respective pressure, the state of dry ice would be gas and solid phase, which eventually represent more than one phase in one particular state.
- In every matter or substance, transition plays a significant role. In the phase of matter, if the substance or matter changes its phase from one to another, then the uniformity will remain constant or unchanged. On the other hand, if the state of matter undergoes a state change, then the uniformity of the substance or matter may get affected.
- In the phase of matter, the phase of substance will change or converted to another phase, and the procedure is called a phase transition. In-state of matter, the state can be altered by changing factor like temperature, as it directly impacts the internal energy of the substance and results in a change in state.
Chemistry is a branch of science that discussed and explains various compositions and properties of matter. These two terms are widely used in chemistry to explain the forms acquire by a substance in certain conditions. The phase of matter and state of matter are quite similar terms that represent a various form of a substance or matter.
The main difference between these two is the uniformity of the chemical and physical properties. Although they explain the same concept. The state of matter is considered a precise and more specific term as compared to the phase of matter. The categorization of the forms in both of these concepts is the same and includes the widely used forms, solid, plasma, liquid, and gas.
