Furthermore, high-energy physics research can create an even more energetic state of matter, the so-called quark-gluon-plasma.

In particular, several particle detectors rely on phase transitions. Phase transitions often occur in nature, but they are also used in many technologies. Hence, plasma is a gas of free electrons and ions. Here, some of the orbital electrons are not bound to atoms or molecules anymore. A state of matter with very high energy is plasma. For example, a liquid such as water starts becoming a gas when it is heated to its boiling point or starts to freeze when it is cooled to its freezing point. When external conditions (such as temperature or pressure) change, the state of matter might change as well.


Matter occurs in different states: solid, liquid, gaseous and plasma.
